In the field of protein content determination, the Folin phenol method has long been adopted by laboratories and production enterprises due to its high sensitivity and wide applicability. However, this method is sensitive to the acidic and alkaline environment of the reaction system, and the choice of buffer system directly affects the reliability of the colorimetric results. EPPS buffer is becoming a noteworthy auxiliary reagent in Folin phenol method due to its unique physicochemical properties. Meet the pH requirements of the detection system The color reaction of Folin phenol method needs to be carried out under weakly alkaline conditions, and high or low pH can interfere with the binding efficiency between copper ions and proteins, thereby affecting the final content of the generated blue complex. The pKa value of EPPS is approximately 8.0, which precisely covers the pH range required for this method. When EPPS is added to the reaction system, it can quickly respond to acid-base changes caused by reagent mixing or environmental factors, stabilizing the pH within the most suitable range. This buffering capacity is not instantaneous, but runs through the entire reaction process, providing a stable chemical environment from the initial interaction between proteins and copper ions to the addition of Folin reagent for color development. Avoid interference with the color development process Many traditional buffering agents encounter a practical problem in the Folin phenol method - they may undergo side reactions with colorimetric reagents or compete with proteins to bind copper ions, resulting in increased background absorption and decreased linearity of the standard curve. EPPS is a zwitterionic buffer that does not participate in redox reactions and does not produce non-specific coloration with the phosphomolybdic acid phosphotungstic acid component in Folin reagent. This means that during the measurement process, the changes in absorbance captured by the detector mainly come from the target protein, rather than the background noise caused by the buffer. This low interference characteristic enables clear and distinguishable signals to be obtained from low concentration protein samples, improving the practicality of the method. Improve comparability of data between batches In protein content detection, the repeatability of results between different experimental batches is an important indicator for measuring the reliability of the method. The use of EPPS buffer reduces fluctuations caused by human made reagent preparation or environmental temperature changes due to its precise pH control ability. Even if measured by different operators at different times, as long as the buffering conditions remain consistent, the difference in color intensity can be controlled within a small range. For work that requires long-term tracking of sample protein content, this stability can help establish more reliable data sequences. Good compatibility with the testing process EPPS has good water solubility and does not cause an increase in solution turbidity or protein precipitation at conventional concentrations. This is particularly important for the Folin phenol method, as any precipitation phenomenon can interfere with optical path measurements. At the same time, EPPS has stable properties at common experimental temperatures and can be used for a long time without special storage conditions. From buffering agents to reliable results Reasonable selection of buffering agents is one of the key steps in the successful protein content determination of Folin phenol method. EPPS has demonstrated unique value in this classic method due to its suitable buffering range, good chemical inertness, and low interference properties on color reactions. For personnel engaged in biochemical analysis or related product quality control, focusing on optimizing the buffer system can help obtain more stable detection results. The EPPS buffer provided by Desheng New Materials has undergone strict quality control and can meet the protein quantification needs in laboratory and industrial scenarios.

In the formula design of personal care and daily chemical products, the balance between thickening, suspension, and stability is always the technical key. Carbomer and its derivative acrylic resin crosslinked polymer, with its unique physical and chemical properties, have become an ideal choice among many high-end shampoo, gel and skin care systems. Its core advantages are reflected in the following four dimensions. 1, Gentle and safe, laying the foundation for application After systematic toxicological evaluation and long-term application practice, Carbopol has demonstrated excellent biosafety. When in contact with human skin and ocular mucosa, it is gentle in nature and does not cause any irritating reactions. Research data shows that the safety threshold of this ingredient is even higher than that of common salt (sodium chloride), which provides a solid safety guarantee for its wide application in demanding categories such as sensitive muscle care and child care. In addition, its molecular structure is not easily utilized by microorganisms as a nutrient source, and it has good anti-corrosion performance. Its stable properties reduce the dependence of the formula on high-efficiency preservatives, which helps to create a milder and more stable product system. 2, Suspension stability, optimizing product performance In systems such as shampoo that require the dispersion of insoluble particles (such as silicone oil, dandruff agents, microcapsules), acrylic resin crosslinked polymers exhibit excellent suspension stability. Compared to traditional cellulose or guar gum derivatives, the network structure formed by it is more efficient and can achieve a more uniform suspension effect at a lower dosage, ensuring that the active ingredients remain uniformly distributed throughout the product shelf life. For low foam or easy defoaming cleaning systems, this ingredient can also significantly improve the texture of foam, extend the durability of foam, and make the structure of foam more delicate and dense, so as to achieve a balance between mild decontamination and ideal skin feedback in the cleaning process. 3, Rheology adjustable, expanding formula boundaries The Carbopol series products provide a rich range of rheological solutions. By flexibly adjusting its dosage or neutralization degree, the viscosity and consistency of the product can be accurately adjusted, and the thixotropy of the gel system can be significantly improved - the fluidity is enhanced under the shear force, which is easy to apply; Quickly restore structure and maintain form after stillness. This feature ensures that the product is easy to spread during use and remains stable when standing still. More importantly, acrylic resin crosslinked polymers have good salt resistance properties. Even in systems containing high concentrations of salt components, their viscosity remains stable and is less affected by fluctuations in solution pH and electrolyte concentration. This provides more formula flexibility for developing high-performance products. 4, Convenient to use, improving production efficiency From the perspective of production operations, the convenience of using Carbopol is particularly prominent. Its powder has the characteristic of rapid wetting, without the need for complex pre dispersion equipment or long-term shear stirring, and can complete hydration and dissolution in a relatively short time. Compared to traditional thickeners such as cellulose, which mainly provide thickening effects, acrylic resin crosslinked polymers can construct efficient suspension networks at low concentrations. For functional ingredients or decorative particles that are difficult to dissolve in the formula, they can provide effective carrying and suspension capabilities. This series of features effectively shortens the production cycle, reduces energy consumption and labor costs, and brings efficiency improvements to large-scale production. The carbomer sold by Hubei Xindesheng Material Technology Co., Ltd. is a very fluffy white powder substance that becomes a viscous transparent substance after preparation. Adding it to various skincare products not only does not affect its effectiveness or appearance, but also has certain benefits.

Tris buffer has become a commonly used reagent in biochemical and molecular biology experiments due to its stable pH range and good biocompatibility. During the preparation process, we often set the concentration and pH value first, and the ion strength is basically fixed at this time. But if subsequent experiments find that the ion strength deviates from the ideal range, how should it be adjusted? This issue may seem subtle, but it directly affects the reproducibility and accuracy of experimental results. Why does ion strength need to be finely controlled Ionic strength affects the interactions between molecules in a solution, affecting enzyme activity, protein solubility, and even nucleic acid hybridization processes. When the pH and concentration of the buffer solution have reached the standard, but the ionic strength does not meet the experimental requirements, simple acid-base adjustment is no longer advisable - whether it is increasing or decreasing the amount of hydrochloric acid, it will directly change the pH value of the buffer system and disrupt the previously accurately adjusted acid-base balance. At this point, a method is needed to independently regulate ion strength without interfering with pH. Enhancing Ionic Strength: Precise Intervention of Inert Salts When it is necessary to increase the ionic strength, adding sodium chloride or potassium chloride is a mature and reliable method. This type of strong electrolyte completely dissociates in water, effectively increasing the total ion strength of the solution, and its ions do not participate in the acid-base balance of Tris, which does not cause significant fluctuations in pH. During operation, the corresponding mass of salt can be directly weighed and added to the buffer solution through theoretical calculation based on the target ion strength. After sufficient dissolution, the adjustment is completed. This method is simple and direct, especially suitable for experimental scenarios such as electrophoresis and chromatography that require high ion strength. Reducing Ionic Strength: The Characteristics of Cleverly Using Buffer Systems If it is necessary to reduce the ion strength, the situation is slightly different. At this point, it is not possible to "dilute" the ion strength by adding electrolytes, as any additional salt will further increase the ion concentration. A feasible approach is to reduce the content of Tris itself in the buffer system. Due to Tris's excellent buffering performance, its pH value can remain relatively stable with appropriate dilution. In practical operation, an appropriate amount of deionized water can be added to the original buffer solution to reduce the Tris concentration and thus lower the ion strength. It should be noted that this method is more suitable for use within a certain range of allowable concentration changes. If the dilution factor is too large, it is still necessary to retest and adjust the pH to ensure the maintenance of buffering capacity. Details and considerations in operation Whether adding salt or diluting, it is recommended to do so under conditions of sufficient stirring and constant temperature to avoid local concentration unevenness or temperature changes affecting the calculation of ion strength. If the experiment requires high ion strength, a conductivity meter or ion strength calculation software can be used for verification to ensure that the adjusted buffer solution is consistent with the target conditions. In addition, recording the amount of addition and final ion strength at each step helps to establish a traceable operational process and improve the standardization of the experiment. The ion strength regulation of Tris buffer is not complicated, the key is to understand the impact of different regulation methods on the system. When increasing ion strength, rely on the stable dissociation of inert salts; When reducing ion strength, use Tris's own buffering properties for moderate dilution. By mastering these two methods, one can flexibly meet the differentiated requirements of various experiments for ion strength without compromising pH, making the preparation of buffer solutions more relaxed and reliable.

In the world of formulas for cosmetics and personal care products, Carbopol plays a role like a "framework architect". This seemingly simple white powder has evolved into multiple models with distinct personalities through different polymerization processes. Faced with the dazzling array of Carbopol 940, 980 in the market U20, Many formulators or purchasers often ask: Can they replace each other? The answer is often negative. Understanding the differences between them is not only a technical task, but also a crucial step in determining the texture and stability of the product. Exploring the source of model differences: different "molecular skeletons" During the polymerization of Carbopol, significant differences exist in the molecular weight distribution and molecular structure of the final product due to variations in the crosslinking agent materials used (such as pentaerythritol, allyl sucrose, etc.) and the degree of polymerization. This is like using the same type of bricks to build a bungalow, high-rise building, or bridge, with vastly different load-bearing capacities and uses. Common Carbopol models in the market, such as 940, 980 U20, Their molecular weights can range from tens of thousands to millions. This inherent "molecular skeleton" difference directly determines their thickening efficiency, emulsification stability, ion resistance, and rheological properties in applications. Therefore, replacing these different "skeleton" materials at will poses a risk of the formula system collapsing. Mainstream model features: "performance responsibility" with each having its own strengths Cabom 940: Clear and transparent "gel expert" Carbopol 940 is known for its short rheology, high viscosity, and high clarity. It can form extremely transparent gel after neutralization, giving the product a refreshing visual experience. Due to its relatively low ion resistance, it is more suitable for playing an advantage in pure systems or formulas with low electrolyte content, such as common gel water, refreshing facial mask and essence. The product formulated with 940 often has a clear and smooth skin feel, without heavy burden after use, making it a refreshing formula suitable for oily or combination skin. Carbopol 980: The 'Structural Master' for Moisturizing and Resistant Resistance Compared to 940, the molecular chain of Carbopol 980 is larger, which gives it higher viscosity efficiency and superior shear and ion resistance. Even in systems containing certain electrolytes or complex active ingredients, 980 can still maintain stable thickening and suspension performance. In skincare applications, 980 is more suitable to be paired with moisturizing formulas. It can form a comfortable and friendly protective film on the skin, bringing a moisturizing and non sticky silky touch. Whether it is moisturizing face cream, sunscreen or essence requiring suspended particles, 980 is a reliable choice for stable system. Carbopol U20: An easy-to-use and versatile 'balance expert' As a new generation of easily dispersible copolymers, Carbopol U20 represents a balance between ease of use and performance. It has excellent self wetting ability and is not prone to clumping during the dispersion process, greatly reducing the difficulty of the production process. U20 has multiple functions of thickening, emulsifying and stabilizing to a certain extent, and can meet the wide demand of products from gel to cream, even containing electrolyte. Its existence provides more creative space for formulators, especially in complex formulas that require a balance between freshness and certain suspension ability. The core of formula selection: respecting differences and precise matching In summary, different models of Carbopol play irreplaceable roles in thickening, emulsification, suspension, and skin sensation regulation. Carbopol 940 is the preferred choice for creating visually refreshing products due to its high transparency; Carbopol 980, with its powerful structural ability and moisturizing sensation, supports the backbone of high-end moisturizing formulas; Carbopol U20, on the other hand, has become the "lubricant" in multifunctional formulations due to its ease of use and wide compatibility. Arbitrary substitution may lead to the decline of gel transparency, viscosity collapse, poor shear resistance of the product, and even irreversible consequences such as delamination. Therefore, when developing products, it is essential to have a deep understanding of the "temperament" of each type of carbomer, respect their performance differences, and accurately select the corresponding model based on the ultimate requirements of the formula - whether it is the pursuit of ultimate freshness or the desire for nourishing care - in order to create high-quality products. This is not only about technical rigor, but also about responsibility for consumer experience. The carbomer sold by Hubei Xindesheng Material Technology Co., Ltd. is a very fluffy white powder substance that becomes a viscous transparent substance after preparation. Adding it to various skincare products not only does not affect its effectiveness or appearance, but also has certain benefits.

In the vast world of biochemistry, glucosidase is like a magical key that unlocks the mysteries of numerous life processes. From medical diagnosis to the food industry, from pharmaceutical research and development to environmental protection, the activity and stability of glucosidase have always been the focus of attention for researchers. In this exploration journey, ACES buffer has become an indispensable "behind the scenes hero" in assisting glucosidase research with its unique advantages. 1, Stable pH, the foundation that safeguards enzyme activity Enzymes, as catalysts in living organisms, are greatly influenced by environmental pH values in terms of their activity and stability. Glucosidase is no exception, as high or low pH can disrupt its fine spatial structure, leading to a decrease in catalytic efficiency or even complete deactivation. Therefore, maintaining a constant pH environment is particularly important in the enzymatic determination of glucosidase. ACES buffer, with its excellent pH buffering ability, has become an ideal choice for this task. It can accurately adjust and maintain the pH value of the reaction system, providing a stable working environment for glucosidase. Whether under acidic or alkaline conditions, ACES can effectively resist the influence of external pH fluctuations, ensuring that enzyme reactions occur under optimal pH conditions, thereby safeguarding the cornerstone of enzyme activity. 2, Low interference, ensuring the authenticity of experimental data In addition to a stable pH environment, the ionic strength and osmotic pressure of the buffer are also important factors affecting enzyme reactions. High ion strength or high osmotic pressure may interfere with the binding of enzymes to substrates, and even alter the structure of enzymes, thereby affecting the accuracy of experimental results. ACES buffer also performs well in this regard. It has low ionic strength and osmotic pressure, which can minimize interference with enzymes and substrates to the greatest extent possible. This means that glucosidase assays performed in ACES buffer can more accurately reflect the catalytic activity of the enzyme, providing researchers with more precise and reliable experimental data. 3, Precise regulation and skillful assistance in experimental design In the enzymatic determination of glucosidase, in addition to pH value, factors such as temperature, substrate concentration, and enzyme concentration can also affect the rate of enzyme reaction and the amount of product generated. Therefore, the cleverness of experimental design often determines the success or failure of research. ACES buffer not only provides a stable pH environment, but also offers the possibility for precise regulation of experimental design. Researchers can flexibly adjust the concentration and pH value of ACES buffer according to specific research needs to meet the requirements of different enzyme reaction conditions. Meanwhile, ACES buffer has good compatibility with various substrates and enzymes, making experimental design more flexible and diverse, providing a powerful tool for researchers to explore the mysteries of glucosidase. 4, Desheng quality, the choice to build scientific research trust Among numerous ACES buffer manufacturers, Desheng stands out with its stable products, high purity, and small inter batch differences.

In the field of medical testing, the collection and processing of blood samples are crucial, and EDTA anticoagulant, as a commonly used specimen type, has a profound impact on the accuracy of test results through its correct use and standardized operation. Today, let's delve into the relevant knowledge of EDTA anticoagulant. Reverse blood collection to prevent clots The preparation of whole blood test specimens depends on the adequacy of anticoagulation. After blood collection, the blood collection tube must be reversed 5-8 times as soon as possible. This simple operation step has significant importance as it can effectively prevent the formation of small blood clots. If this operation is ignored, small blood clots may interfere with the subsequent testing process, leading to biased test results and affecting the doctor's judgment of the patient's condition. So, the timely reversal operation after blood collection should not be underestimated. Timely inspection to avoid errors EDTA salt anticoagulation is a non irreversible anticoagulation method, which determines that the EDTA anticoagulation test should be completed within 24 hours after blood collection in the test tube. Once this time limit is exceeded, certain components in the blood may undergo changes, which may lead to errors in the test results. For example, the morphology and function of blood cells may change over time, affecting the detection values of various indicators. Therefore, arranging the inspection time reasonably and ensuring the completion of the testing work within the prescribed time limit is an important prerequisite for ensuring the accuracy of the results. Properly preserve and maintain stability Different blood cell counts have different requirements for storage conditions. White blood cell count can be stored for 48 hours at 4 ℃, while it does not exceed 24 hours at 23 ℃; Platelet count can be stored for 24 hours at 4 ℃. Understanding and following these storage conditions can maximize the stability of blood samples, ensure that the state of blood components during testing is as consistent as possible with that during blood collection, and provide guarantees for accurate testing. Precise quantity control to prevent changes The anticoagulant process requires a sufficient amount of EDTA, but excessive use can cause problems. Excessive EDTA may cause morphological changes in blood cells, which undoubtedly have adverse effects on the test results. Therefore, it is particularly important to accurately control the amount of EDTA dipotassium added. In practical operation, inspectors need to strictly follow the standard operating procedures and accurately measure the amount of EDTA dipotassium to avoid affecting the quality of testing due to improper dosage. Understand the characteristics and apply them reasonably EDTA salt has the effect of inhibiting platelet aggregation, but it should be noted that it cannot completely prevent platelet aggregation. This characteristic requires inspectors to fully consider the possible partial aggregation of platelets when analyzing test results, in order to avoid misjudgment. At the same time, corresponding measures should be taken during the collection and processing of blood samples to reduce the influence of external factors on platelet aggregation. Coordinated use and standardized operation EDTA dipotassium can be used in combination with sodium fluoride and separation gel. When used in combination, there is a clear addition standard, that is, when EDTA dipotassium/sodium fluoride is used, 1.2-2.0mg dipotassium and 2-4mg sodium fluoride should be added per milliliter of blood. Strictly following this standard for operation can ensure that various reagents play their best role, improve the accuracy and reliability of detection. Radiation sterilization to ensure safety After adding relevant substances to the blood collection tube, irradiation sterilization is an essential step. It is recommended to use gamma ray irradiation at a dose of 8-25kGy, which can be determined based on the initial bacterial count. Through irradiation sterilization, microorganisms inside the blood collection tube can be effectively killed, ensuring the sterile state of the blood collection tube, preventing contamination of blood samples during collection and storage, and ensuring the authenticity and safety of test results. The correct use of EDTA anticoagulant involves multiple steps and details, from the processing after blood collection to the control of testing time, from the control of storage conditions to the accuracy of reagent dosage, and then to the standardized operation of sterilization. Each step is closely connected and jointly affects the accuracy of the test results. Only by strictly following these usage precautions can high-quality blood samples be provided for medical testing and reliable basis be provided for disease diagnosis and treatment. Hubei Xindesheng Material Technology Co., Ltd. has been researching and producing blood collection tube additives such as EDTA dipotassium for nearly 20 years. The performance of various products produced not only meets relevant standards, but also meets the customized needs of customers.

In the silky texture of cosmetics, the stable efficacy of pharmaceutical products, and the strong adhesion of industrial products, there is a seemingly insignificant substance that plays a crucial role - carbomer. It is like an invisible magician, endowing numerous products with unique performance through clever thickening techniques. Carbopol originally existed in the form of powdered resin, with its molecules tightly curled up like snails curled up in a shell, making its thickening ability difficult to exert. When it is dispersed in water, the molecules will undergo hydration with water, resulting in a certain degree of stretching. However, even if the concentration of the aqueous solution reaches a certain level before neutralization, its thickening effect is still not satisfactory. This is like a dancer with unlimited potential, but constrained by their hands and feet, unable to perform graceful dance moves. The key to unleashing the powerful thickening power of Carbopol is to transform its acidic state into the appropriate salt. This transformation process is like injecting vitality into carbomer molecules. Using inorganic bases such as sodium hydroxide, potassium hydroxide, ammonium hydroxide, or low molecular weight organic amines to neutralize carbomer can ionize its molecules and generate negative charges along the polymer backbone. At this point, the repulsive force between same-sex charges begins to take effect, and the originally curled up molecules quickly straighten out, forming an open structure. This process is fast and efficient, with the thickening effect achieved instantly, and the solution changes from thin to thick and stable. Texture shaper in the field of beauty In the world of cosmetics, Carbopol thickening technology can be regarded as a master in shaping texture. For essence, its texture becomes more mellow and delicate after being thickened by Carbomer. Applied to the skin, it can spread evenly and form a lightweight protective film, giving the skin a silky touch. At the same time, it can also help the effective ingredients in essence to better adhere to the skin surface, improve the absorption efficiency of ingredients, and bring more lasting nourishment to the skin. In the lotion, the thickening effect of Carbomer makes the water oil two phases can be better fused, avoiding the occurrence of stratification, so that the lotion can always maintain a uniform and stable texture, making it more comfortable to use. The Stable Guardian of the Pharmaceutical Industry In the field of medicine, products thickened with carbomer have become the guardians of stability. Some ointment and gel for external use can be applied to the affected part more accurately by virtue of the thickening property of Carbomer. The protective film it forms not only isolates bacteria and pollutants from the outside world, but also has a moisturizing effect, creating a good healing environment for wounds or lesions. At the same time, Carbopol can also release drugs slowly and continuously, improve the efficacy of drugs, reduce the frequency of administration, and alleviate the pain of patients. A reliable helper for industrial applications The industrial sector also relies on the assistance of Carbopol thickening. In paint production, Carbopol thickening can adjust the viscosity of the paint, making it easier to control during the application process. Both brushing and spraying can achieve a uniform effect, improving the quality and appearance of the coating. In terms of adhesives, the thickened carbomer enhances the viscosity and cohesion of the adhesive, improves its bonding strength and durability, enabling it to adapt to more complex working environments and meet the diverse needs of industrial production. With the continuous advancement of technology, Carbopol thickening technology is also constantly innovating. Researchers are exploring more environmentally friendly and efficient neutralizing agents to further enhance the thickening effect of Carbopol and the overall performance of the product. At the same time, the application scope of Carbopol is constantly expanding, and it is expected to play an important role in more emerging fields in the future. The Carbopol produced by Hubei Xindesheng Material Technology Co., Ltd. is mainly used in the cosmetics field. Desheng has rich research and development experience and professional technical personnel. In addition to providing professional usage advice, it can also provide customized services.

In the early stages of life, every expectant parent yearns to know: Is the baby healthy? In the past, obtaining accurate answers often required invasive methods such as amniocentesis, which brought psychological pressure and intangible risks to pregnant women. Nowadays, with just one tube of pregnant woman's venous blood, it is possible to accurately screen for chromosomal diseases in the fetus - this is the revolutionary change brought about by non-invasive prenatal genetic testing. Behind this change, there is an unknown but crucial 'guardian' - free DNA preservation solution. It is pre installed in a special blood collection tube, guarding the trace fetal code in the blood and providing protection for subsequent precise detection. The 'fetal messenger' in maternal blood In 1997, Professor Lu Yuming discovered the presence of free fetal DNA in the peripheral blood of pregnant women, which completely overturned the pattern of prenatal diagnosis. Originally, during pregnancy, placental trophoblast cells undergo normal apoptosis, releasing short DNA fragments into the maternal bloodstream. These fragments are like "miniature messengers" sent from the fetus, carrying all the genetic information of the fetus. However, these messengers are extremely fragile and rare. In early pregnancy, fetal free DNA accounts for only 5% to 10% of the total free DNA in maternal plasma. What's even more concerning is that after the blood is separated from the body, the mother's white blood cells will gradually lyse, releasing a large amount of maternal genomic DNA, which quickly overwhelms these weak fetal signals like a surging tide. If there are no special protective measures, the sample will be "distorted" just a few hours after blood drawing, and cannot truly reflect the chromosomal status of the fetus. Three major functions, precise protection It is in this context that specialized blood collection tubes containing free DNA preservation solutions have emerged. It is not just an ordinary vacuum tube, but a "mobile laboratory" that integrates multiple technological contents. This preservation solution plays three key roles in non-invasive screening: 1. Stabilize blood cells and prevent interference. The preservation solution contains special cell metabolism inhibitors that can quickly penetrate into blood cells, "immobilizing" these nucleated cells from the source and preventing them from rupturing and releasing genomic DNA during transportation. This is like maintaining order in a noisy venue, ensuring that only the original weak signals can be heard, thereby ensuring the purity of the detection background. 2. Protect DNA and resist degradation. There are naturally occurring nucleases in the blood that can cleave free DNA like scissors. The anti nuclease components in the preservation solution can effectively inhibit the activity of these enzymes, like putting a layer of "protective clothing" on precious fetal DNA to protect them from degradation. 3. Transport at room temperature, breaking down barriers. Traditional testing often requires low-temperature cold chain transportation, which is costly and prone to chain breakage. High quality free DNA storage tubes can achieve stable storage at room temperature for up to 3 to 14 days, which means that pregnant women in remote areas can also enjoy testing services that are homogeneous with those in first tier cities. From a tube of blood to a report The role of free DNA preservation solution in non-invasive screening runs through the entire detection process, and every step cannot be separated from its protection: 1. Sample collection and transportation. When nurses use blood collection tubes containing preservation solution to extract blood from pregnant women, protection is immediately activated. The preservation solution quickly mixes into the blood, stabilizing cells and inhibiting nucleases. Subsequently, the sample can be sent to a testing center thousands of miles away at room temperature, without the need for cold chain and without fear of delay. 2. Plasma separation. After receiving the samples, the laboratory separates the plasma through gradient centrifugation. Thanks to the protection of the preservation solution, the original proportion of fetal free DNA is still maintained in the plasma at this time. Without this layer of protection, the separated plasma may have already been contaminated by maternal background DNA, and the test results would be meaningless. 3. Detection and analysis. Extract free DNA from plasma and perform sequencing and analysis. Clinical data shows that samples protected by high-quality preservation tubes have a detection sensitivity and specificity of over 99% for the three most common chromosomal aneuploid diseases - Down syndrome, Edwards syndrome, and Patao syndrome.

Early screening of tumors, as the name suggests, refers to the detection of early or even very early malignant tumors in healthy or high-risk populations. Traditional screening methods, such as imaging examinations, are often difficult to characterize small lesions; As the gold standard for diagnosis, tissue biopsy cannot be used as a large-scale screening method due to its invasiveness. It is in this context that liquid biopsy technology has entered the clinical field, and free DNA preservation solution is the basic support to ensure the practical application of this technology. The tumor code in the blood Circulating free DNA refers to highly fragmented DNA fragments that are free outside of cells in the blood. In a healthy human body, it mainly comes from normal cells undergoing aging and apoptosis. But when a tumor occurs, the situation changes. Tumor cells have a fast proliferation rate and high apoptosis rate, constantly releasing their DNA into the bloodstream. This free DNA from the tumor is called circulating tumor DNA. This type of tumor DNA carries genetic variation information consistent with the primary tumor, including mutations, methylation, copy number variations, etc. In theory, with just one tube of blood drawn, signals from tumors throughout the body can be captured. However, this ideal state faces a serious challenge in reality: the tumor DNA content in the blood is extremely low. Especially in early cancer patients, tumor DNA accounts for only a very small proportion of total free DNA in plasma, sometimes even less than one thousandth. To extract these trace amounts of information from the vast background of blood cells, sample quality becomes the first step in determining success or failure. The two major threats after leaving the body After blood is separated from the body, the sample is not stationary. If there is no intervention, two problems will quickly occur. One is the instability of blood cells. After being isolated, nucleated white blood cells in the blood gradually undergo apoptosis or lysis, releasing a large amount of genomic DNA. These DNA do not come from tumors. When they flood into the plasma, they dilute the already extremely weak tumor signals like a flood. The second is the degradation effect of nucleases. There are naturally occurring nucleases in plasma, whose function is to clear free nucleic acids, which can lead to further fragmentation or even disappearance of valuable tumor DNA fragments. Ordinary blood collection tubes are unable to address these two issues. In traditional EDTA tubes, blood must undergo plasma separation within a few hours, otherwise the sample will 'deteriorate'. For tumor early screening projects that require centralized testing or remote testing, this time window is obviously difficult to meet practical needs. Triple function of preservation solution The free DNA preservation solution is designed to address the aforementioned issues. It is pre sprayed on the inner wall of a dedicated blood collection tube and starts working from the moment blood flows into the tube. Its primary function is to stabilize blood cells. The preservation solution contains special cell metabolism inhibitors that can quickly act on white blood cells, preventing their rupture and release of genomic DNA. This is like closing the door to pollution at the source, ensuring that only the original free DNA in the blood is retained in the plasma. Secondly, it is to protect the existing DNA. The anti nuclease components in the preservation solution can inhibit the activity of nucleases, providing a layer of "protection" for free DNA to prevent its degradation. The third is to provide a transportation window. High quality preservation solution can keep samples stable at room temperature for up to 3 to 14 days. This means that the geographical distance between sampling points and detection centers is no longer a barrier, and remote areas can also enjoy detection services that are homogeneous with those in central cities.
