Ethylenediaminetetraacetic acid (EDTA) is a commonly used anticoagulant for testing, there are three kinds of disodium (EDTA-Na2), dipotassium (EDTA-K2) and tripotassium (EDTA-K3). Routine blood is a common blood test item. In order to ensure that blood does not coagulate when blood is drawn, blood collection tubes containing anticoagulant are currently used. The commonly used anticoagulant is EDTA dipotassium (EDTA-K2). That is, its anticoagulant effect is very good, and it has little effect on the shape of blood cells. Because potassium salt is more soluble than sodium salt, EDTA-K2 and EDTA-K3 are better than EDTA-Na2; and because the pH of EDTA-K2 is lower than that of EDTA-K3, it can compensate for cell wrinkles caused by osmotic pressure. shrink, so come out. EDTA-K2 pollution often causes abnormally high K concentration in patients, which is inconsistent with the clinical manifestations of patients. However, EDTA-K2 pollution may also affect other biochemical indicators, but how much EDTA-K2 concentration affects which conventional biochemical indicators What about the impact? This article by the lippi.g team in Biochem Med (Zagreb) systematically explores the effect of increased concentrations of adherent EDTA-K2 on the results of routine biochemical assays. Materials and methods: This paper recruited 15 volunteers from the laboratory staff to be included in the study. Two vials of lithium heparin and one vial of EDTAK2 samples were collected from each study subject. EDTA whole blood was diluted with lithium heparin blood into samples containing lithium heparin at concentrations of 0%, 5%, 13%, 29% and 43% EDTA. Next, the samples were separated and tested for biochemical indicators: ALT, total bilirubin, total cholesterol, creatinine, iron, LDH, lipase, potassium, sodium, chloride, magnesium, phosphorus. Results: As EDTA2K concentration (from 5% concentration) increased, calcium, cholesterol, iron, lactate dehydrogenase, magnesium test results decreased, but potassium increased. The EDTA concentrations that significantly increased the results of the sodium phosphate assay were 13% and 29%, respectively. With the increase of the concentration of EDTA, the results of ALT, total bilirubin and lipase did not change. Low concentrations of EDTA2K (from 5%) have greater effects on calcium, cholesterol, lactate dehydrogenase, magnesium and potassium. For sodium phosphorus iron, it is necessary to have a high EDTA2K (from 29%) to have an effect.

Carbomers usually come in the form of a fluffy, white, hygroscopic powder and may have a slight acetic acid odor. There are many types of carbomers available on the market, and the main uses are basically the same, the difference is the type of process solvent used ( benzene or non-benzene), the type and amount of crosslinking agent used, and the addition of optional additives to improve wetting and dispersion. Carbomer is a non-toxic substance with little or no potential to irritate skin and eyes at concentrations used in cosmetics and personal care products, so it is an important ingredient in cosmetics and pharmaceuticals. In its powder form, it needs to be used after preparation, and it is mainly used in these fields in the form of gel.Each carbomer particle is actually a macromolecule containing many linear PAA chains that are cross-linked together. After carbomer cross-linking, the result is that these macromolecules are not truly water-soluble. Instead, cross-linked hydrophilic PAA The mass of the chain is only water dispersible and water swellable. Unlike non-crosslinked PAA, which dissolves in solution to form polymer coils, overlapping and entanglement with increasing concentration, carbomers disperse in water and swell upon neutralization, forming a microgel solution. Our company ,Hubei Niew desheng Materials Technology Co., Ltd. is a professional manufacturer of carbomer. It has a professional carbomer R&D and production team with 17 years of experience and rich product knowledge. There are 940 and 980 models of Carbomer currently produced.

Foreign vacuum blood collection tubes were used during World War II as early as the 1930s, while my country is relatively backward. From the early 1990s, a very small number of companies began to develop and produce vacuum blood collection tubes. Subject to raw materials and technology, the development was relatively slow. . After more than ten years of development, my country's blood collection tube enterprises not only meet the domestic demand for blood collection tubes, but also export their products to foreign markets. The vacuum blood collection tube has the characteristics of accurate and safe blood collection, good effect of separating serum and plasma, easy to use, and can collect blood samples from multiple tubes with one needle. Therefore, we often see it when collecting blood in the hospital. Common blood collection tubes include PST tube, SST tube, EDTA tube, PRP tube, and CPT tube. What is the function of each? PST tube, the full name of Plasma Separator Tube in English, we often use it to represent the plasma separation rubber tube. Generally, a light green head cover tube is used. It combines serum separation gel and heparin sodium or heparin lithium anticoagulant to separate blood cells from serum and plasma to improve its output. , to ensure that the composition of plasma is stable, it is often used for electrolyte testing, and is often used for plasma biochemical testing in intensive care and emergency care in hospitals. SST tube, English full name Serum Separator Tube, inert separation and coagulation tube, generally used as yellow head cover tube. The coagulant in the tube can accelerate blood coagulation. After centrifugation, the serum separation gel in the tube can separate the liquid components (mainly serum and plasma) and solid components (mainly blood cells, proteins) in the blood, and form a stable in the tube. Barrier, sample specimens can be stored for 48 hours. This tube is mainly used for emergency serum biochemical and immunological detection. EDTA tubes, also known as EDTA anticoagulant tubes, generally use purple capped tubes. EDTA anticoagulants will use EDTA salts (dipotassium, tripotassium, disodium), because they have good chelation of calcium ions, thereby inhibiting the effect of thrombin to prevent blood coagulation. Since this coagulation is reversible, it needs to be detected within a certain period of time (generally no more than 24 hours). Compared with other anticoagulants, the EDTA salt has little effect on the coagulation of blood cells and the morphology of blood cells. It is generally used for blood routine testing, and is also suitable for the collection, transportation and storage of venous blood samples for nucleic acid testing. The serum separation gel in the tube can It can well block the interference of hemoglobin in red blood cells to nucleic acid detection experiments. PRP tube, English full name Platelet Rich Plasma, also known as PRP rapid extraction tube, is a high-end blood collection tube, which is often used in medical beauty projects. High-concentration plasma, and then inject it into the required parts, so as to achieve the effect of cosmetic repair and regeneration or treatment.CPT tube, full name in English, Cell Preparation Tube, vacuum mononuclear cell preparation tube, separates lymphocytes and mononuclear cells from whole blood through serum separation gel of different specific gravity, used in clinical medical testing, mainly to check HLA or residual leukemia genes Testing, TB testing, HIV testing, etc. Although different vacuum blood collection tubes are used in different fields, their purpose is to use the different specific gravity of serum separation gel to separate the blood components that need to be detected or extracted. At present, there are very few manufacturers on the market that support customized separation gels. Desheng Biochemical has continuously developed through 16 years of technical team. After four generations, the separation gel has the characteristics of anti-irradiation, good separation effect, stable quality and long storage time. Between 1.045-1.065g/cm3. Desheng separation glue can be divided into acrylate system and resin system according to different raw materials. The appearance includes transparent, translucent and opaque, and can be customized according to customer appearance requirements. The products produced are favored by more than 400 enterprises at home and abroad, and sell well in domestic and overseas markets.

For example, common Tris-HCL, TAE, TES, Bis-Tris, etc. are synthesized from it. . This article will introduce the TRIS derivative TES and Bis-Tris in detail. 1. TES (Tris ethanesulfonic acid) TES Chinese name: Tris ethanesulfonic acid, CAS number: 7365-44-8, TES has a structure similar to Trizma, and is one of the ethanesulfonic acid series physiological buffers developed by Good et al. It meets various standards of "Good" buffers , although the structure is a neutral molecule, it still behaves as a zwitterion in solution. TES has a pKa of 7.4 (physiological pH), making it a very versatile biological buffer. TES is suitable for use in a variety of cell culture systems that require divalent metal ions, whereas many other buffers (such as citrate or phosphate) cause chelation or precipitation reactions that make this requirement unsatisfactory. In addition, TES is extremely beneficial to study the succinic acid oxidation reaction. 2. Bis-Tris (bis-trimethane hydrochloride) Bis-Tris full name in Chinese: Bis (2-hydroxyhexyl) amino (trimethylol) methane, CAS number: 6976-37-0, is an inert zwitterionic buffer, its solution varies with temperature There are only slight changes from the constant. Bis-Tris can ionize hydrogen ions in a small amount, has weak acidity, and is suitable for weakly acidic buffer systems. Due to the introduction of two hydroxyethyl groups in Tris, there are many atoms providing lone pairs of electrons, and it has complexing ability for some metal ions. EDTA or Bicine are similar. Bis-Tris is suitable for the separation of hemoglobin, and can protect the stability of hemoglobin during freeze-dried storage. Useful as an effective buffer for assays of muscle enzyme activity. 2-D gel electrophoresis is used as the catholyte in isoelectric focusing electrophoresis (IEF).

Heparin is a class of naturally occurring anticoagulants present in all mammals, hence its name because it was first isolated from liver tissue in 1916. Heparin is synthesized in mast cells and basophils and stored in the secretory granules of these cells. Since mast cells are present in many tissue types, heparin can be derived from this range of extrahepatic tissues. Currently, heparin preparations are often derived from the mucosal intima of pig intestines. Heparin prevents blood clotting due to the unique pentasaccharide sequence contained in its structure that binds tightly to antithrombin 3. Antithrombin 3 is a plasma protein that inhibits blood clotting by binding to several activated coagulation factors, including factors such as XIa, Xa, IXa, and IIa (thrombin), which inhibit their enzymatic action. Heparin blocks the fibrin formed by the coagulation cascade, which is required for blood clot formation. This anticoagulant effect of heparin can occur in vitro and in vivo. Heparin sodium is a natural heparin salt used in medicine and laboratories. Lithium heparin is a laboratory-specific in vitro anticoagulant prepared from sodium heparin by cation exchange chromatography. Heparin is the only anticoagulant used to prepare samples for blood gas analysis. Heparin can interfere with the results in two ways. The first is high heparin concentrations in the blood, and the second is heparin thinning the blood if liquid rather than dried (lyophilized) heparin is used. Traditional blood gas analytes (pH, pCO2, and pO2) are less affected than electrolytes (especially ionized calcium), which are also measured by modern blood gas analyzers. Therefore, if only pH, pCO2, and pO2 are measured, the sample requirements are less stringent in the case of heparin. For these analytes, it is still important that the heparin (sodium or lithium) concentration is less than 200 IU/mL blood and the blood dilution does not exceed 5%. The electrolytes included in the test track preclude the use of sodium heparin and the use of lithium heparin. One of the common practical problems associated with blood gas analysis is insufficient anticoagulation and the formation of small blood clots that can block the sample path of the blood gas analyzer and invalidate the results. Inadequate mixing of the sample with heparin is often the problem. The lower the heparin concentration, the greater the risk of insufficient anticoagulation and related problems due to poor mixing techniques. Desheng Biochemical is a manufacturer specializing in the production of heparin sodium and heparin lithium for in vitro anticoagulants. Since its establishment in 2005, it has 17 years of rich R&D and inspection experience, and can accurately control the quality and potency of heparin. The conventional packaging of heparin produced by Desheng comes in 10g and 50g bottles, and the shelf life is 3 years. Since it is the source manufacturer, not only the quality is guaranteed, but the price is also very advantageous.

Carbomers are effective at increasing viscosity in aqueous systems at relatively low levels, with most carbomers capable of producing viscosities of 10,000–60,000 cP when used at only 0.5% w/w. Therefore, carbomers are commonly used as aqueous thickeners in various products. However, the real use of carbomer lies in its ability to impart high yield values ​​to formulations. Yield value is the resistance of a fluid to initial flow when stress is applied, and at rest, a tightly packed carbomer microgel network behaves as an elastic solid that resists deformation. The network does not begin to flow until a critical level of shear stress (i.e. yield stress) is applied, at which point the microgels can slide past each other, resulting in fluid flow. When heterogeneous phases, such as emulsion droplets, are dispersed in a carbomer-thickened formulation, the microgel network captures and stabilizes them against fluids at rest, ie, below the yield stress. However, when a stress in excess of the yield stress is applied, the fluid flows smoothly, enabling product dispensing and application. For this reason, carbomer is used to formulate countless products. Carbomer is easily dispersed in water and mixtures of polar organic solvents and water, such as 70% w/w ethanol-water. When initially prepared, aqueous dispersions of hydrated carbomer particles are acidic and typically exhibit a pH of 2.5-3.5, depending on the polymer concentration. These dispersions do not have significant viscosity and may be cloudy prior to neutralization with alkaline pH adjusters such as sodium hydroxide or triethanolamine. After neutralization of the carboxylate groups, the carbomer becomes ionized and expands to hundreds of its original volume due to electrostatic repulsion between the negatively charged carboxylate groups and osmotic expansion due to trapped counterions times to obtain a microgel dispersion. Hubei Xindesheng Material Technology Co., Ltd. is a professional manufacturer of carbomer. It has a professional carbomer R&D and production team with 17 years of experience and rich product knowledge. There are 940 and 980 models of Carbomer currently produced.

As the cumulative number of confirmed cases in China Jilin, Guangdong, Shandong and other places continues to increase, the nationwide nucleic acid detection has become the norm. The virus preservation solution is an important liquid medium added to the nucleic acid detection sampling tube. The commonly used virus preservation Liquids can be divided into VTM, UTM, MTM types. The standard UTM and VTM preservation solutions are designed to transport intact viable microbial or virus samples and culture them, so there are still biological hazards, which will be introduced in detail today. These three types of preservation solutions. MTM type virus preservation solution MTM is a molecular transport medium that provides users with a timely "snapshot" of that sample by preserving and stabilizing DNA and RNA. MTM (Molecular Transport Medium) is designed and optimized for molecular detection, allowing safe and efficient collection, transport and processing of pathogenic samples. Including qPCR and next-generation sequencing, it uses a unique patented technology to safely collect samples from patients with highly infectious diseases. It was first launched in 2006 in preparation for a global pandemic and has been used to detect many infectious and high-consequence pathogens, including influenza, RSV, tuberculosis, HIV and coronavirus. VTM and UTM type virus preservation solution In some foreign countries, both VTM and UTM refer to virus preservation solution. The full name of UTM is universal transport media, which is literally translated as universal transport medium. In virus sampling tubes, it refers to virus preservation solution. The VTM and UTM here usually refer to non-inactivated preservation solutions. Some manufacturers, VTM is more targeted than UTM, specifically for the preservation and transportation of virus samples. Although VTM or UTM cannot inactivate the virus, it can also be used for virus surface antigen or antibody detection in addition to nucleic acid detection because it preserves the integrity of the virus. In fact, the inactivated and non-inactivated virus preservation solutions do not say which one is better. Desheng can provide both kinds of preservation solutions according to the requirements of different manufacturers' products and testing environment. Advantages of MTM type virus preservation solution 1. Another major advantage of MTM is that samples can be safely stored for up to 7 days at ambient temperature or 28 days at 2 to 8°C and can be reused multiple times. In addition to reducing the risk of handling live pathogen samples, this also reduces costs by eliminating cold chain requirements and the need for Category 3 facilities as testing can be performed outside of the container 2. Once the swab or biological fluid is added to the MTM, the user gets a "snapshot" of the inactivated microbial sample in time. The microbial DNA, and more importantly, the labile RNA, is immediately stabilized and preserved at the sampling point. Therefore, samples in MTM do not have to be pre-treated to BLS-III or even BLS-II safety levels, only safe routine laboratory testing practices are required. These three virus preservation solutions have been introduced, and I believe that everyone's doubts can be answered. Desheng is a professional virus preservation solution manufacturer, and its quality has been recognized by many. Although the epidemic situation in many places is still severe recently, as long as everyone is united and united, I believe that we will soon see the dawn of the dawn, and everything will eventually return to the original beauty and tranquility.

HEPES and CHAPS buffer are both commonly used buffers in biochemical testing. The full chemical name of HEPES is 4-hydroxyethylpiperazine propanesulfonic acid, which is a zwitterionic buffer. It is a white powdery solid at room temperature. High water and water solubility. The chemical name of CHAPS is 3-[(3-chloroaminopropyl)dimethylammonium]-1-propanesulfonate, which is also a white powder and has good water solubility, but also hydrophobicity at the molecular level . When CHAPS is dissolved in water, the appearance of its aqueous solution will be a colorless to pale yellow transparent color. Application of HEPES buffer Since the growth and metabolism of cells in culture can cause dramatic changes in the environmental pH of the medium, it is necessary to add an appropriate amount of biological buffer to maintain an environment in which cells can be stably cultured. HEPES buffers in the pH 6.8-pH 8.2 range, which is beneficial for cell culture. So HEPES is widely used in cell culture, tissue culture, protein purification and extraction, immunoprecipitation, cell lysis, live cell imaging and other biological and biochemical studies. Application of CHAPS Buffer Several studies have shown that, compared with NP-40 and Triton X-100, CHAPS can gently and effectively disrupt the nuclear membrane, solubilize membrane proteins, and disrupt protein-protein interactions (PPIs). In addition, CHAPS can preserve the native state or conformation of the protein, and can maintain the activity and function of the protein. Therefore, CHAPS is widely used in biological science research fields, such as cell lysis and protein purification. It is important to note that when preparing any solution using CHAPS, try not to shake or agitate vigorously. Desheng Company is a manufacturer engaged in the research, development and production of biological buffers. The HEPES and CHAPS products currently produced have stable performance, good use effect and a purity of 99%. If you need to buy, welcome to inquire and order

Carbomer is a thickening agent that helps control the viscosity and flow of cosmetic products. They also help distribute and suspend insoluble solids into liquids and prevent separation of the oily and liquid portions of the solution. They have the ability to absorb and retain moisture and can expand up to 1000 times their original volume when dispersed in water. Typically, this type of ingredient is used in gel-like formulations because it forms a colloidal, mucus-like consistency when mixed with water. In cosmetic ingredient lists, the name carbomer is sometimes associated with numbers, such as 910, 934, 940, 941, and 934P. These numbers represent only the specific molecular weight and composition of the polymer. This ingredient is included in a variety of personal care products, such as styling gels, facial moisturizers, sunscreens, shampoos, and here are a few of the properties of carbomers. emulsification Additionally, carbomers are capable of dispersing or suspending insoluble solids in liquids. Therefore, carbomers are used to prevent separation of emulsions into oil and liquid components, as well as to control the consistency of cosmetic and other skin care products. By adding carbomer to products like shampoos, conditioners, creams and lotions, formulas will appear richer, smoother and creamier. texture By varying the amount of carbomer used in a product, formulators can create anything from a firm hairspray that stays exactly where it is placed, a lotion that has body but still flows easily, or a rich cream that retains its shape. Large amounts of carbomer in the gel may cause the product to roll or clump on the skin, but this phenomenon depends on other formulation steps taken to minimize this effect. skin benefits Interestingly, carbomer doesn't seem to have any effect on the skin. Once you apply carbomer on your skin and it dries, you won't even notice it. Carbomer does not make the skin sticky, dry or tight. Carbomer polymers are not in the product to promote any benefit, only to improve the texture of the product. Other uses In addition to being used in personal care products, carbomer polymers have a wide range of commercial and industrial uses. Some examples include use as fragrance carriers, medical bandages, wound dressings, and flame retardant gels, to name a few. Is carbomer safe? The safety of Carbomer has been assessed by the Cosmetic Ingredient Review Panel of Experts, which evaluates the safety of skin care and cosmetic products. Carbomer polymers exhibit low phototoxicity, light contact sensitization, skin irritation and sensitization at concentrations up to 100%. After evaluating the scientific data, a CIR panel of experts concluded that carbomer polymers are safe as ingredients in cosmetic and personal care products.

EDTA dipotassium is an anticoagulant commonly added in clinical collection vessels, which is commonly used as blood routine in blood testing items. So does it apply to biochemical detection items? Today we are going to talk about common biochemical tests. Biochemical tests have many indicators, such as liver function test, renal function test, myocardial enzyme test, blood lipid and blood glucose test, etc. These tests seem to have little relationship with EDTA dipotassium, but they also add raw materials such as chromogens and enzyme preparations. EDTA dipotassium products are needed for hemoglobin and whole blood tests alone.   In clinical biochemical examination items, if EDTA dipotassium blood collection anticoagulation tube is used for biochemical examination, high potassium, low calcium, low magnesium, low ALP and other effects will occur. Why do you say that? They are listed as follows:   1. EDTA dipotassium itself contains potassium ions, resulting in high blood potassium.   2. EDTA can chelate calcium ions in blood samples resulting in low calcium.   3. EDTA chelates magnesium ions in blood samples, resulting in a decrease in blood magnesium. Note: In addition to calcium ions and magnesium ions, EDTA also chelates other divalent metal ions, such as manganese ions, iron ions and so on.   4. Magnesium ion is the activator of ALP activation center, so EDTA dipotassium also reduces ALP activity.   In conclusion, due to the infiltration and dilution effects of EDTA dipotassium, it may have an uncertain impact on the data accuracy of biochemical examination items. In order to avoid these effects, correct anticoagulants should be selected in different tests. Desheng Biochemical develops and manufactures various vascularized anticoagulants, including heparin, EDTA potassium sodium salt, potassium oxalate, trisodium citrate, etc. If necessary, please contact Desheng, and the sales manager will recommend appropriate anticoagulants to you according to your needs.
