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.  

There are two kinds of blood collection additives: coagulant and anticoagulant, among which heparin series and EDTA series are widely used in the market. In addition to these anticoagulants, there is also an anticoagulant reagent "potassium oxalate". How many people know the anticoagulant function principle of potassium oxalate? The following will lead you to know potassium oxalate. Potassium oxalate as an anticoagulant has the advantage of high solubility, and its action mechanism is easy to understand. The dissolved oxalic acid reacts with calcium ions in the blood to form calcium oxalate precipitation. Therefore, the coagulation function of calcium ion itself is invalid, which prevents the coagulation process of calcium ion. The concentration of potassium oxalate anticoagulant is usually mixed with blood in the ratio of 1:9, and the concentration is 0.1mol/l. Not too high concentration of potassium ion can easily lead to dehydration and contraction of blood cells. Therefore, in order not to affect the volume and morphology of red blood cells, the mixing proportion of anticoagulants must be quite appropriate when measuring hematocrit. Although potassium oxalate is used in many aspects of blood biochemical determination, some determinations are not appropriate. For example, the determination of potassium and calcium ions, blood smear examination, etc. In addition, potassium oxalate cannot be used for differential counting of platelets in leukocytes and blood cells, because potassium oxalate can cause platelet aggregation and affect the basic morphology of leukocytes. It can be concluded that potassium oxalate, as a popular product in anticoagulant, is affected by these specific factors. At present, there are few manufacturers of potassium oxalate in China, and our company is a professional manufacturer of blood collection additives. At present, the company's blood collection additives include heparin potassium, heparin lithium, EDTA dipotassium / sodium, EDTA Tripotassium, coagulant, high-efficiency coagulant powder, water-soluble silicide, oil silicon, potassium oxalate, trisodium citrate, sodium fluoride and other products. In addition to exploiting vascular additives, our company also produces biological buffer series, chemiluminescence reagent series, chromogen substrate series, enzyme preparation series, Carbomer and virus preservation solution. Hubei xindesheng Material Co., Ltd., as a professional manufacturer of blood collection additives, has decades of R & D and production experience.

If you are willing to cooperate with our products, you can contact relevant personnel on our official website for consultation. Desheng welcomes your visit.

Enzyme is an active substance existing in nature. These substances have a very far-reaching impact on our life and health. Enzyme manufacturers can prepare various types of enzymes in different ways to meet different production needs, such as the needs of biochemical detection, food processing and so on. So how do these manufacturers choose cost-effective enzyme manufacturers? 1. Select manufacturers with rich varieties There are many kinds of enzymes in nature, each of which can play different roles. When used in production, sometimes a variety of enzymes may need to be added due to the needs of process technology. Therefore, in order to achieve one-stop procurement, manufacturers should try to choose enzyme manufacturers with a wide variety of enzyme preparations, so as to ensure that the purchased enzyme preparations have the same quality, Desheng has more than ten years of experience in the production and R & D of enzyme preparations. There are dozens of enzyme products, which can meet the needs of various production enterprises. 2. Select manufacturers with excellent raw material quality The production of various enzyme preparations needs to use different molds for fermentation. In this process, whether the quality of raw materials is excellent or not can determine the quality of enzyme preparations. In order to ensure the purchase of the best enzyme preparations, the manufacturer should choose the enzyme preparation manufacturer with high requirements for the quality of raw materials, which can not only maintain the reliable quality of enzyme preparations, At the same time, it can also ensure that the product quality processed by the enterprise is better. Desheng's enzyme preparation is specially used in biochemical detection and biochemical experiment, which has better purity and activity than industrial enzyme preparation. 3. Select manufacturers with good technology Although most enzyme preparations are refined after fermentation, with the continuous development of science, technology and industry, the processes of various enzyme preparations are also improving. The use effect of enzyme products produced by enzyme preparation manufacturers with better processes will be better. Therefore, the production process should also be considered when selecting enzyme preparation manufacturers. The above three points are the methods for Desheng Xiaobian to select enzyme preparation manufacturers. No matter what type of enzyme preparation the enterprise needs or the purpose of using enzyme preparation, it is very important to select an enzyme preparation manufacturer with high cost performance in order to purchase high-quality and effective products. Therefore, the purchaser should have a comprehensive understanding of the enterprise, Select the best manufacturer after comprehensive comparison.

Chemiluminescence immunoassay is not only the fastest developing and popularizing immunoassay method, but also the most advanced labeled immunoassay technology. Its sensitivity and accuracy are several orders of magnitude higher than enzyme immunoassay and fluorescence method. It can completely replace radioimmunoassay and completely eliminate enzyme-linked immunoassay. It mainly has the advantages of high sensitivity, strong specificity, low reagent price, stable reagent and long validity period (6-18 months), stable and rapid method, wide detection range, simple operation and high degree of automation. The chemiluminescent reagent used as a marker shall meet the following conditions: Luminol and acridine ester luminescent agents are commonly used labeling luminescent agents, which meet the following conditions: 1. Can participate in chemiluminescence reaction. 2. It can form a stable conjugate reagent after coupling with antigen or antibody. 3. After coupling, high quantum effect and reaction kinetics are still retained. 4. The physicochemical properties, especially immune activity, of the labeled substances should not be changed or rarely changed. Classification of markers used in chemiluminescence immunoassay 1 Direct chemiluminescent agent Direct chemiluminescent agent refers to the direct labeling of antigen or antibody with chemiluminescent agent, which mainly includes the following types. ① When acridine ester is oxidized by H2O2 under alkaline conditions, it emits light with a wavelength of 470nm and has high luminous efficiency. Its excited state product N-methyl acridone is the illuminant of the luminous reaction system. Acridine ester luminescent agents can be directly used to label haptens and proteins. When used to label antibodies, the binding is stable, the production of light quanta is not reduced after binding, and high specific activity can be obtained, which is conducive to the establishment of two site chemiluminescence immunoassay. Acridine ester is an ideal luminescent substrate. ②Tripyridine ruthenium tripyridine ruthenium is an electrochemiluminescence agent. It and electron donor tripropylamine (TPA) can lose an electron on the surface of the anode electrode at the same time. 2 Enzymatic reaction luminescent agent: the luminescent agent (substrate) emits light by the catalysis of labeled enzymes (horseradish peroxidase and alkaline phosphatase). ①The luminescent agent catalyzed by horseradish peroxidase is luminol and its derivatives; In addition, isoluminol and its derivatives have chemiluminescence properties. Luminol is the first synthesized luminescent substance. ②The luminescent substrate catalyzed by alkaline phosphatase is amppd, amppd It is a new chemiluminescent agent. There are two important parts in its molecular structure. One is the dioxygen ring connecting benzene ring and adamantane, which can break and emit photons; The other is the phosphate group, which maintains the stability of the whole molecular structure.

Hearing about the virus made us feel terrible. Especially last year's COVID-19, let the whole world smell it. What does this have to do with ourVirus Transport Media? As the name suggests, virus preservation liquid is the liquid to preserve virus. It is to prevent it from harming us, so that we can better understand, understand, study and analyze it, and then overcome it.   The Virus Transport Media is a liquid for sampling virus swabs in the tube to sample the swabs. It is mainly used for the collection, preservation and transportation of common virus samples such as New Coronavirus, hfmv, influenza virus and so on. It can be used to collect tissue samples from throat swabs, nasal swabs or specific parts. The stored samples can be used for subsequent clinical experiments such as nucleic acid extraction or purification. It is usually divided into two types, one is non inactivated and the other is inactivated; The non inactivated type can protect virus protein and nucleic acid, preserve virus activity and facilitate culture and detection; The inactivated type makes the virus no longer have physiological activity, lose infection and pathogenicity, and have fecundity. It can inactivate the virus, eliminate secondary infection, and protect the safety of transportation and testing personnel.   How do we choose theVirus Transport Media? Since the virus is a parasitic organism, it cannot survive in vitro after sampling. If it cannot be detected in time, it needs to be stored in theVirus Transport Media. In order to protect the safety of the virus detection environment and the safety of detection personnel, we need to use our virus inactivation preservation solution.   But the inactivated preservation solution doesn't make the virus inactive. Can it be detected? In fact, the purpose of using inactivated preservation solution is to cleave nucleic acid, release nucleic acid, and then detect nucleic acid through follow-up real-time fluorescent RT-PCR, so as to judge whether the sample contains virus characteristic nucleic acid, that is, whether it is infected with virus. The virus has a single structure and contains only one nucleic acid and protein. Therefore, the virus is detected when the characteristic nucleic acid is detected.   Under what circumstances do we use non inactivatedVirus Transport Media? The non inactivated preservation solution is mainly an improved virus maintenance solution based on the transport medium. This one is to retain the protein shell of the virus and virus nucleic acid DNA or RNA at the same time, so that the virus has the integrity of protein antigen epitope and nucleic acid in vitro. Of course, there is a certain risk of infection in case of misoperation. Strict low temperature is required for long-term storage after sampling.   No matter what kind ofVirus Transport Media is used, not all samples can be transported and preserved at the sample collection place after virus sampling. Therefore, we need to transport and retain the collected virus swab, otherwise the virus nucleic acid will degrade quickly and the nucleic acid cannot be detected, Therefore, it is necessary to add preservation solution to the sampling tube to prevent the nucleic acid of the virus from being degraded so quickly. At the same time, after sampling, it shall be tested as soon as possible or strictly stored at low temperature to ensure that the detection is accurate.Virus Transport Media plays an important role in maintaining the stability of virus samples due to the rapid reproduction and variation of virus.

Luminol is also known as luminescent ammonia, and its English name is 5-Amino-2, 3-dihydro-1, 4-phthalazinedione. It is a yellow crystal or beige powder at room temperature. It is a relatively stable chemical reagent. Luminol reagent is a mixture of luminol and hydrogen peroxide, which is mainly used for blood detection in modern criminal investigation. Luminol reagent is a reagent to identify blood. Even if the blood is wiped, heme in the blood will remain. When luminol reagent is sprayed on heme, it will oxidize with reactive oxygen species and release blue purple fluorescence. Known as the luminol reaction. It is an organic substance used to identify blood. However, luminol also has some shortcomings in criminal investigation. For example, if the crime scene is completely treated with bleach, the fluorescence emitted by luminol will strongly cover up the existence of any blood stains. Or the animal blood at the crime scene is confused with the test blood, which will affect the test results. In addition, luminol also reacts with animal excreta, which is almost the same as the light emitted from the blood. In addition, luminol needs to be used in a dark environment, and luminol's luminous time is limited, so it is necessary to make detection records when luminol is luminous. Although there are some factors affecting luminol at the criminal investigation site, there will be some countermeasures. For example, when bleach is mixed into the blood, we can adopt the drying method to dry the site for a few days, and the effect of bleach will be greatly reduced. Luminol and acridine ester are commonly used chemiluminescent reagents. Luminol has been recognized to react with OH radical to cause luminescence, superoxide anion radical or singlet oxygen and H2O2 in alkaline medium Desheng biotechnology has been making chemiluminescent reagents for many years. Luminol is the representative of chemiluminescent reagents. Desheng biotechnology has developed and produced products for many years, which can fully meet the requirements of various manufacturers with reliable quality and favorable price.

Carbomer 940 is a thickening agent and gel used widely in the daily chemical industry. It includes sterile disinfectant gel and carbomer. Moreover, the temperature has dropped rapidly recently, the epidemic has a tendency to rebound, and the demand for carbomer has also increased. What is the price now? Carbomer 940 is commonly used in the carbomer series, because skin feels good, thickening, viscosity and transparency are very suitable for skin care products such as creams, wash hands and hand sanitizers. Although there are many manufacturers producing Carbomer, due to its various uses, the quality and grade of carbomer used in different products are different, so the price is also obviously different. Take Desheng carbomer 940 as the raw material of daily chemicals as an example. If it is a ton, the price is about 130 per kilogram. The same Carbomer, the same concentration of products with different gel transparency, the raw material prices are also different. The products with excellent thickening performance and high transparency also include carbomer of Lubrizol. However, because they are imported products, the price is relatively high, and they do not need to be purchased from retail agents, so the supply is not flexible enough. Although there are many domestic producers of Carbomer, although the price is lower, there is still a certain gap between the quality of many products and those imported. Especially for high-end cosmetics, the cost of raw materials is not high, and the cost of carbomer is less. Therefore, the carbomer with better quality is preferred as the raw material of gel or cream. This is why before the epidemic, most manufacturers used imported carbomer raw materials, and the imported carbomer began to use domestic raw materials only when the epidemic was limited. There are also some carbomer prices due to different grades. For example, in the field of material industry, the price of carbomer leak proof adhesive modified by decoration materials is much lower; In the pharmaceutical field, Carbomer used as pharmaceutical excipients has higher grade and higher price than that used in cosmetics. It can be seen that the same is carbomer 940. The price difference is relatively large for different grades and quality. Desheng's carbomer 940 is used for cosmetics and pharmaceutical accessories.

According to the feedback from the market to Carbomer, the transparency of carbomer has always been concerned by the majority of customers. A lot of carbomer powder can be made when it is powdered, but when it is dissolved, you will find that the gel penetration is not enough enough to meet the requirement. Due to the special structure of Carbomer, it is easy to expand with water, and it has strong hydrophilicity. The carbomer hygroscopicity of dry powder is very strong, which is the same as other hygroscopic powders. Therefore, when it is put into water or other polar solvents by improper methods, it is easy to form clusters or incomplete wetting. In this way, the gel will appear granular and transparent. In addition, in some gel products, such as disinfectant and free gel, in order to increase permeability, anticorrosion and solubilization, ethanol is often added as an additive. The content can be as high as 75%. Carbomer gel is essentially a polymer aqueous solution. The stability of polymer solution is due to the existence of hydration film on the surface of the particle. The addition of strong hydrophilic non electrolytes (such as ethanol) will make the polymer solution flocculate. The carbomer ethanol gel prepared by different operation processes has different concentration of ethanol, and when the concentration of ethanol is too high, The finished gel will produce a little milky light and reduce the transparency of the gel. Therefore, if 2% of the purified water is added to the gel product with 70% ethanol content, the milk light will be significantly reduced compared with the finished products. This method has a certain effect on improving the appearance transparency of the finished products. The big difference between Desheng carbomer and ordinary carbomer on the market is that in the powder state, it can be seen that the powder of Desheng carbomer is obviously white, and the powder is more fluffy and delicate. Moreover, the transparency of our carbomer is much higher than that of similar products. You can see the opposite sky through our kapom!

Acridine chemiluminescence reagents mainly include acridine ester and acridine sulfonamide. Acridine ester is a very important chemiluminescence reagent with high quantum yield. The chemiluminescence efficiency of acridine ester is relatively high, which is generally five times or more than five times that of luminol. In addition, the chemiluminescence process of acridine ester reacts rapidly and has low background. It can emit light in the presence of sodium hydroxide and hydrogen peroxide. In the process of oxidation reaction, the conjugate is decomposed and does not affect the luminescence of free acridine ester. In addition, the chemiluminescence reagents of acridine ester series have very good stability and convenient storage. In recent years, with the development of chemiluminescence application technology and instruments, especially the expanded application of acridine ester series products, it has a very significant effect. There are many types of acridine esters, such as acridine ester dmae-nhs. This paper will introduce the dmae-nhs of acridine ester. At present, there are many processes for the synthesis of acridine ester dmae-nhs, which can be attributed to the seven step method. For the shortcomings of this method, such as difficult reaction steps, high cost of raw materials and reagents, which is not conducive to large-scale preparation, the traditional seven step method is optimized, and a new five step chemical reaction method for the synthesis of acridine salt is developed. Acridine ester dmae-nhs was synthesized from 3,5-dimethyl-4-hydroxybenzoic acid and acridine 9 carboxylic acid through five steps of esterification, condensation, hydrolysis, succinyl amination and methylation. Based on the above understanding, the synthetic method and evolutionary history of acridine salt dmae-nhs. In Hubei xindesheng Material Technology Co., Ltd., acridine ester has been produced and developed for more than ten years. Among them, acridine ester series has many models: acridine ester (dmae-nhs, nsp-dmae-nhs, me-dmae-nhs), acridine salt (nsp-sa, nsp-sa-nhs), acridine hydrazide nsp-sa-adh and other products. In addition, Hubei xindesheng materials can also provide blood collection additives, biological buffers, enzyme preparations, Carbomer, virus preservation solution and other products. If you want to know about the products, you can call for consultation. Desheng welcomes your call.

Heparin lithium heparin sodium is a common additive for heparin tubes. This year, customers who purchased heparin lithium reported some problems to our company. For example, the doctor used heparin tube to operate blood for electrolyte analysis, and found that blood potassium and blood sodium were on the high side. Why? After receiving the customer's feedback, we first conducted repeated tests on the same batch of heparin lithium produced by our company to determine that its various indicators are normal. We plan to explore the answer from two aspects. One is to find the implementation conclusion of experts on the Internet and explore the answer from the professional perspective of doctors. 10g heparin lithium package per bottle The problem was found according to the medical and clinical literature. The effect of heparin lithium on the determination of electrolyte was understood by comparing the results of plasma anticoagulated with heparin lithium and serum without anticoagulant. The method used is to select two samples of different additives of the same object at the same time, a total of 40 samples for comparison. The results showed that heparin lithium anticoagulant had a significant effect on the determination of blood potassium, but there was no significant difference in the determination of blood sodium and blood chlorine. The experimental conclusion is that heparin lithium has an effect on the determination of blood potassium. It is suggested that non anticoagulant samples should be used for the determination of electrolyte. The results showed that compared with serum without anticoagulant, heparin had no effect on the determination of blood sodium and blood chlorine, but there was a difference in blood potassium. Heparin lithium anticoagulant has a significant effect on the level of potassium in electrolyte determination. From the cause analysis, it is probably that heparin and potassium generate heparin potassium, which affects the determination of potassium by ion selective electrode, resulting in low blood potassium. At the same time, for serum samples, due to the destruction of platelets in the process of blood coagulation, the potassium ion in platelets (its concentration is much higher than plasma potassium) releases human blood, making the serum higher than plasma potassium, The increase was positively correlated with the number of platelets. Serum potassium heparin lithium can not accurately reflect the real level of potassium in the body due to the fragmentation of platelets in the real process of evacuating serum after blood coagulation, so it is initiated to use plasma potassium instead of serum potassium. According to the same common clinical experience, although there is the effect of platelet destruction, the determination of serum potassium is still due to the determination of plasma potassium. The tension is that serum potassium has no effect of heparin, and serum is widely accepted as a sample in the old biochemical examination and analysis in China. From the perspective of the experience of professional doctors, this conclusion is also created. Heparin products represented by heparin lithium and heparin sodium have significant anticoagulant performance after blood collection. Whole blood cell count and blood cell examination are often used. Desheng biochemical is deeply engaged in the field of vascular preparations, and has more than 20 independently developed patented technologies. Ensure that the products obtained by customers are better than the average level of peers and enjoy high-quality after-sales technical service.

The chemiluminescence labeling method represented by acridine ester and luminol is the preferred scheme for the quantitative detection of ligand conjugates. These assay markets have a high demand for technology, which requires detection technology to be highly sensitive, less susceptible to interference and easy to use. The chemiluminescence process has sufficient sensitivity, so it is very suitable for these applications. Old fashioned assays require the separation of bound markers from unbound markers. Although the assay is easier to develop, it is somewhat complex to implement. On the contrary, the chemiluminescence labeling method represented by acridine ester adopts homogeneous determination, which affects the luminescence reaction in some way through the combination of ligand and its receptor, which is easy to observe and the dose required for the reaction is small. Chemiluminescence is a series of radioisotope based analytical procedures. Its feasibility is proved to be applicable to various analytes, including high molecular weight and low molecular weight substances. The stability and analytical performance of reagents are of great significance to improve and maintain high-quality analytical performance. Most importantly, the development of ICMA technology based on labeled antibodies has the potential to increase the sensitivity of determination. This technique may prove valuable in testing and monitoring infectious agents and tumor markers. We have done experiments in which the natural luminol reaction product is incorporated into globulin, and the luminescence of its derivatives is 100 times that of diazonium salt. This also confirms the potential of Lumino. Chemiluminescence of luminol and acridine ester occurs under alkaline conditions, although in the case of luminol, there are catalyst requirements. The catalyst can be a simple transition metal cation, such as Mn + + or Ni, but it can also be complex macromolecules, such as horseradish peroxidase and cytochrome. The most popular catalyst is micro peroxidase because of this efficient reaction. Under relatively mild conditions. This requirement for catalysts makes the reaction vulnerable to the interference of substances in biological samples and powerful. Desheng bio produces chemiluminescent reagents, such as luminol, isoluminol, acridine ester, etc. In addition, it also independently develops and produces dipotassium and Tripotassium EDTA, with high purity, content of more than 99.5%, good anticoagulant effect and no impurities. After detection by SGS inspection organization, the content of trace elements is one order of magnitude lower than the national and industrial standards (10 times), with good clarity and high solubility. 80 grams of dipotassium and Tripotassium can be quickly dissolved per 100ml of water at 25 ℃, It can maintain the original properties of blood to the greatest extent and has no significant impact on the blood clinical test results. It has been favored and affirmed by well-known enterprises at home and abroad, including Yangpu!
