What are the effects of coagulant and water-soluble
2021-07-04
siliconizing agent on vacuum blood collection tube detection Coagulation is caused by adding foreign substances to the blood. The external pathway activates the clot to form a clot through biochemical action. Plastic tubes need to be sprayed with blood coagulant to ensure rapid and dense clot formation. The greater density of blood procoagulant surface sites accelerates clotting time. Silica (such as glass, diatomaceous earth) accelerates the formation of clots by contacting blood to accelerate clot formation, and the complete coagulation is formed in about 30 minutes. The amount of blood coagulant varies from manufacturer to manufacturer. The coagulant also facilitates the separation of potential fibrin formation in serum. Conducive to the performance of prothrombin. Although these clot activators can quickly clot for 10 to 20 minutes, the clot is not easily separated from the serum. The blood coagulant can be added to the tube by forming beads, which can act with the carrier on the inner tube surface. The clot activator is quickly suspended in the blood. When the clot starts, the carrier can be dissolved in the serum and the clot at the same time. Recently, the project that Desheng Biochemical participated in assisted the customer to release a fast serum test tube containing thrombin; the orange stopper quickly activates the blood clot within 5 minutes. It can ensure that the rapid serum test tube and other commercially available serum test tubes have the same clinical results. In the study, Desheng Biochemical found that the problem with some blood coagulation accelerators is that they must be mixed thoroughly to allow the clot to settle completely. If soluble fibrin clots form, they can interfere with the accuracy of the pipetting device or solid phase binding in immunoassays. Plasma gas can be used to introduce heteroatoms (non-carbon atoms and hydrogen atoms in the main chain of the molecular structure) into the surface of the tube wall to accelerate blood clotting without contaminating the serum or clot with adhesives or blood coagulants. The proteomic analysis after the blood coagulant promotes coagulation can also be changed by the clot activator. When silicon dioxide and silicate blood coagulant are sprayed on the plastic tube, the active metalloproteinase is released and compounded with the matrix. As a manufacturer of coagulant, Desheng Biochemical, here is a special reminder: in order to obtain a good coagulant effect, determine the best composition of coagulant and water-soluble siliconizing agent, and always add them to different types And the size of the blood collection tube to allow these substances to function normally without adversely affecting the quality of blood samples and test results.

What are the functions of buffers such as Tris and Hepes?
2021-07-05
Tris, Hepes, Mops and other buffers are almost all made up of buffer pairs composed of "weak acid and its conjugate base salt" or "weak base and its conjugate acid salt". You can add a certain amount of other buffers. A substance that slows down changes in PH. These two substances can be buffered toward acid or base at the same time because of the reaction. For example, a mixed solution of acetic acid and sodium acetate is a buffer solution. If hydrochloric acid is added, the pH will not drop too fast, because hydrochloric acid will react with sodium acetate to produce acetic acid. On the contrary, if sodium hydroxide is added, the pH will not increase too fast, because sodium hydroxide will react with acetic acid to form sodium acetate. In many chemical reactions, buffer solutions are used to keep the pH of the solution constant. Buffer solutions are of great significance to the production and evolution of life, because most organisms can only grow within a certain pH range. There are many types of biological buffers, and here will introduce several commonly used biological buffers. 1. Tris buffer: Chinese name Tris(hydroxymethyl)aminomethane, CAS number 77-86-1, white crystalline powder, odorless and tasteless, good water solubility. It is a widely used buffer with a pKa of 8.1 at 25°C and a pH buffer range of 7.0-9.2. It is mostly used in chemical experiments, new coatings, cosmetics and other fields. 2. Hepes buffer: Chinese name 4-hydroxyethylpiperazine ethanesulfonic acid, CAS number 7365-45-9, white crystalline powder in appearance. It belongs to the "Good" buffer and is also one of the most suitable buffers for biological research. It is a zwitterionic organic buffer with a pH buffer range of 6.8-8.2. It is mostly used in cell culture, electrophoresis experiments, cosmetics and other fields. 3. Mops buffer: Chinese name 3-morpholine propane sulfonic acid, CAS number 1132-61-2, white powder in appearance. It is a zwitterionic buffer commonly used in biochemistry and molecular biology. It belongs to the "Good" buffer like Hepes. The pH buffer range of Mops is 6.5-7.9, and the pKa is 7.2 at 25°C. It is mostly used as physiologically related buffers, DNA/RNA extraction kits, PCR diagnostic kits, etc. Nowadays, these buffers are often used in biochemical experiments, so the market demand for such buffers is very large. Therefore, buffer merchants on the market are mixed, making the procurement work very difficult. Recommend a manufacturer here: Hubei Xindesheng Material Co., Ltd. Desheng company has been producing chemical raw materials for decades. Desheng company has a professional team responsible for the development and production of biological buffers, and has imported equipment and raw materials for production and processing. The products produced by Desheng Company are of high quality, fast production efficiency, and sufficient stock in the warehouse.

Is EDTA-Na2 a food additive besides anticoagulant?
2021-07-03
The full name of EDTA-Na2 is disodium ethylenediaminetetraacetate, and it is usually used as a blood anticoagulant. Appearance is white or milky white granular powder, odorless and tasteless, soluble in water, but hardly soluble in ethanol. EDTA-Na2 is an excellent compounding agent in chemistry and a biochemical reagent with a very wide range of applications. However, in our daily life, when shopping in the supermarket, we sometimes find that there are ethylenediamine tetramine in the list of food ingredients. The name of disodium acetate is above. Don't worry about this. Although EDTA-Na2 is a chemical product, it mainly functions as a stabilizer, coagulant, antioxidant and preservative in food processing. In addition, the legal food additives specified in the "National Food Safety Standard Food Additive Use Standards", numbered GB 2760-2014, as long as the corresponding dose is used for the corresponding food category, it will not cause harm to the body. Many foods are protected by EDTA-Na2, and processed foods are treated with antioxidants to avoid deterioration, and can inhibit the proliferation of microorganisms and delay food spoilage, thereby "preserving the image." Therefore, without it, it would be difficult for us to enjoy all kinds of food at will. In addition to being used in food, EDTA-Na2 is also used in the medical field, among which blood anticoagulants are the main ones. It is an important complexing agent, which is mostly used in electroless copper plating, gold plating, aluminum-tin alloy plating, electrochemical polishing of steel parts and the solution before silver plating of copper parts. It can also be used in detergents, liquid soaps, shampoos, agricultural chemical sprays, color photosensitive materials processing bleaching fixers, water purifiers, PH regulators, etc. Here we recommend a manufacturer specializing in the production of blood collection tube additives: "Hubei Xindesheng Material Co., Ltd.". Desheng company produces EDTA-Na2 and also produces EDTA-K2/K3. The main core products are heparin series products and serum separation gel. Desheng company has a professional team to manage production and research and development. Up to now, Desheng company has produced blood collection reagents for more than ten years.

Influence of dipotassium EDTA pollution on the detection of heparin blood biochemical items
2022-03-24
Influence of dipotassium EDTA pollution on the detection of heparin blood biochemical items 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. Hubei Xindesheng Material Technology Co., Ltd. is a relatively old brand of blood collection tube reagent manufacturers. The unit packaging volume of its anticoagulant EDTA dipotassium is 500g/bottle, and the shelf life is 3 years. It has served many domestic and foreign customers and has professional The R&D and production team of blood collection tube anticoagulants have accumulated 17 years of experience, rich product knowledge, stable product performance and good use effect.
