Heparin sodium, a strongly negatively charged substance, is used as a blood collection anticoagulant due to its natural anticoagulant properties. Its mechanism is to bind with antithrombin 3, activate its activity, inhibit coagulation factors, and thus prevent blood clotting. Attention should be paid when using heparin sodium: 1. Refined and purified white powdered heparin sodium should be selected to avoid errors in experimental results caused by crude products; 2. Following the principle of ready to use, it is not advisable to leave the solution for a long time after preparation to prevent bacterial growth; 3. Reasonably controlling the dosage, 1mL of blood corresponds to the best effect of 20IU heparin sodium. Heparin is mainly stored in mammalian organs and is currently obtained through extraction of pig small intestine. Desheng Biochemical has been specializing in the research and development of blood collection tube additives for 17 years, including heparin sodium, heparin lithium, serum separation gel, etc. With rich experience and reliable product quality, we provide professional pre-sales and after-sales services. If you have any needs, please feel free to consult and purchase.

Heparin lithium, as a commonly used anticoagulant in vacuum test tubes, is widely used in clinical biochemical examinations, routine blood testing for ion content, and blood glucose detection. It can effectively inhibit platelet aggregation, promote coagulation factor inactivation, enhance anticoagulant effect, and accelerate plasma centrifugation speed. When measuring blood sodium ions, heparin lithium does not affect the results and has a fast anticoagulation rate. Used in combination with sodium fluoride in blood glucose tubes, it can accurately detect blood sugar. Desheng Biochemical, a Chinese manufacturer of heparin lithium, has been focusing on the research and development of blood collection reagents for 18 years. Its products include serum separation gel, heparin sodium, heparin lithium, etc. The quality is reliable and highly recognized by domestic and foreign customers. Adding about 20IU of lithium heparin per milliliter of blood is most effective. If you have any needs, please feel free to consult and purchase. We provide comprehensive product information and professional services to help you choose the right product.

EDTA dipotassium is an important anticoagulant in vacuum blood collection tubes, commonly used in blood routine and nucleic acid testing. It can chelate calcium and magnesium ions, inhibit coagulation processes, and degrade nucleic acids by nucleases. The dosage should be determined based on the amount of blood collected, with a standard of 1.5-2.2mg per ml of blood, usually taken as 1.8mg/ml. Potassium EDTA is easily soluble in water. When preparing, it is important to note that the concentration should not be too low to avoid dilution effects, and should not be too high to prevent decreased solubility and hemolysis of blood cells. The principle of anticoagulation is the same as that of EDTA tripotassium, except for slight differences in ion concentration and pH. Desheng focuses on the research and production of in vitro diagnostic reagent raw materials, providing high-quality anticoagulants such as EDTA dipotassium and tripotassium to meet the needs of specific testing projects.

Tripotassium EDTA (CAS 65501-24-8), also known as ethylenediaminetetraacetic acid tripotassium, is a white crystalline powder chemical substance that is easily soluble in water and hygroscopic, with a molecular weight of 442.56. As a blood anticoagulant, EDTA tripotassium solution does not damage the effective components of blood and is suitable for routine blood tests, but not for coagulation experiments or calcium, potassium, and sodium ion measurements. The configuration method is simple, only deionized water needs to be used for dissolution, and the water consumption needs to be controlled. When storing, it should be sealed and protected from light at dry room temperature. The prepared solution is recommended to be prepared and used immediately. As a professional manufacturer, Desheng provides high-quality and high-purity EDTA tripotassium and can provide sample testing.

Desheng Science Popularization: Acridine ester, as a chemiluminescence marker, has the characteristics of high sensitivity, no need for enzyme catalysis, and short and strong luminescence. Its basic properties are stable, containing NHS active ester groups, and easily coupled with biomolecules. The luminescence mechanism is the oxidation reaction in alkaline hydrogen peroxide solution, which emits light. The labeling process includes steps such as preparing reagents, dissolving and mixing, avoiding light reaction, and sealing purification. The marking efficiency is evaluated by measuring the luminous intensity. During the labeling process, attention should be paid to light avoidance, reagent purity, reaction condition control, and instrument calibration. The acridine ester labeling technology has been continuously improving with the development of biotechnology and chemiluminescence technology. By improving methods and optimizing conditions, the labeling efficiency and luminescence intensity can be enhanced. As a supplier of acridine esters, Desheng provides high-purity powders with good luminescence performance and high sensitivity, making it the preferred choice for experimenters. Welcome to inquire and purchase!

Luminol (CAS 521-31-3), also known as 3-aminobenzoylhydrazine, is a chemiluminescent reagent with high sensitivity, good selectivity, strong stability, a particularly luminescent color (blue-green), and environmental friendliness. Its luminescence principle is based on the oxidation process of molecular structure under the action of hydrogen peroxide and catalyst. Luminol is easily soluble in alkaline solutions and is used in chemiluminescence immunoassay such as metal cation and blood testing. In criminal investigation, trace amounts of blood can be detected; In biomedical research, biomolecules or cells can be labeled; In environmental monitoring, environmental quality can be evaluated.
