Heparin sodium is a commonly used chemical substance with a wide range of applications. It can not only be used as a drug in vivo, but also can be used as a blood Anticoagulant in vitro, mainly by inhibiting the activity of thrombin and other coagulation factors to prevent blood coagulation. Below is a detailed introduction to the main functions and application fields of heparin sodium.   1、 Anticoagulant effect   Heparin sodium enhances its activity by binding to antithrombin III, thereby inhibiting the formation of thrombin, which can prevent the formation of blood clots. In addition, heparin sodium can further enhance its anticoagulant effect by inhibiting the activity of other coagulation factors, such as thrombin factor Xa.   2、 Blood collection and processing   After being configured as a solution, it is mainly added to a vacuum test tube. When in contact with blood samples, it can inhibit blood coagulation in the test tube, thereby ensuring the stability of the blood collection environment and improving the collection and processing efficiency of medical staff. It generally does not come into direct contact with the human body and will not have any side effects on the human body.   3、 Prevention and treatment of venous thromboembolism   Venous thromboembolism is a serious thrombotic disease, including Deep vein thrombosis (DVT) and Pulmonary embolism (PE). Heparin sodium injection can be used to prevent and treat these conditions, especially in surgery, prolonged bed rest, and high-risk patients. It usually comes into contact with the human body, and its level and purity requirements are high. Generally, manufacturers without qualification certificates are not allowed to produce and sell it.   4、 Hemodialysis and cardiac surgery   Heparin sodium is also commonly used in hemodialysis as a Anticoagulant to prevent thrombosis in dialysis devices and blood vessels. The Anticoagulant during dialysis needs to maintain appropriate anticoagulant effect to ensure the normal circulation and filtration of blood in the dialyzer. In cardiac surgery, heparin sodium is commonly used as anticoagulant therapy to prevent the formation of blood clots during and after surgery. It is usually used in combination with other Anticoagulant (such as Warfarin) to achieve better anticoagulant effect.   5、 Other application areas   Heparin sodium can also be added to daily chemicals to have antioxidant, anti-inflammatory, and promoting blood circulation effects. At the same time, it can not only protect the skin from damage, slow down skin aging, but also reduce skin redness, swelling, inflammation, and increase skin metabolism, thereby improving the poor condition of the skin.   Heparin sodium, as an important anticoagulant, has a wide range of applications. Its anticoagulant effect is achieved by inhibiting the activity of thrombin and other coagulation factors. However, when using, it is also important to pay attention to the amount of addition, and not too much or too little, otherwise it will cause changes in the results. As a professional supplier of heparin sodium, Desheng mainly provides blood collection additives and uses in vitro anticoagulant reagents.

Heparin Sodium is a Anticoagulant widely used in clinical and research fields. It has a long and rich history and originated in the early 20th century. In 1916, an American biochemist named Jay McLean first extracted an anticoagulant substance from pig lungs. He noticed that this substance had the effect of prolonging the clotting time of animal blood, and later became known as heparin.   1、 Naming of Heparin   McLean initially named this substance 'Heparin', which comes from the Greek word 'hepar'. He chose this name because at the time he believed that the liver might be the main source of heparin.   2、 Development of clinical applications   In 1935, American biochemists Karl Meyer and John M. Morehead successfully applied heparin to clinical anticoagulation therapy for the first time. They found that heparin can prevent and treat thrombosis and improve postoperative blood circulation.   3、 Discovery and Research Purification of Heparin Sodium   In 1939, Meyer and Morehead successfully extracted purer heparin through further research, which made the production and application of heparin more feasible and effective. Therefore, in the 1950s, researchers began to transform heparin into heparin sodium to improve its solubility and stability. It has a series of chemical properties and is widely used in clinical blood collection as an extracorporeal blood Anticoagulant.   4、 Improvement of preparation and production technology   Over time, the preparation and production techniques of heparin sodium have been continuously improved and optimized. By improving the extraction, purification, and crystallization processes, the purity and quality of heparin sodium have been improved. So its application fields are also constantly expanding. In addition to anticoagulant therapy and in vitro anticoagulant blood processing, heparin sodium is also widely used in fields such as cardiac surgery, hemodialysis, and laboratory research.   As an important Anticoagulant, heparin sodium has a long history and rich research results.

Therefore, understanding the dissolution method of heparin sodium salt is crucial. Below, we will focus on introducing the dissolution method.   1、 Solvent selection   When dissolving heparin sodium salt, it is necessary to choose a suitable solvent. In general, deionized water and distilled water are the most commonly used solvents, and their pH and ion concentration are close to those of human blood, without significantly affecting the properties of the solution.       2、 Dissolution temperature   Temperature is an important factor when dissolving heparin sodium salt. Normally, heating the solvent to an appropriate temperature can accelerate the dissolution rate of heparin sodium salt, but this operation is carried out under special circumstances. The commonly used operations are to dissolve at room temperature, usually not exceeding 45 degrees Celsius, to avoid reducing the stability of the solution or causing the decomposition of heparin sodium.   3、 Mixing and dissolution time   After adding the solvent, sufficient stirring is required to promote the dissolution of heparin sodium salt. Stirring can increase the contact area between it and the solvent and accelerate the dissolution rate. It is recommended to use appropriate stirring equipment or methods, such as Glass rod, and continue stirring for a period of time until heparin sodium salt is completely dissolved. The dissolution time depends on its form and the properties of the solvent, usually within 10 minutes.   4、 Filtering and Storage   The completely dissolved heparin sodium salt solution can be filtered to remove insoluble substances and impurities. Use appropriate filtration devices and membranes to filter the solution into a clean container to obtain a clear solution. In addition, the storage of solutions is also very important. Generally, solutions should be stored under refrigeration conditions to ensure their stability and long-term preservation.   Dissolving heparin sodium salt is a prerequisite for its use, and the correct dissolution method is crucial to ensure the stability and effectiveness of its solution. The correct dissolution method can ensure the stability of solution quality and performance, thereby ensuring the effective use of heparin sodium salt.

Anticoagulant is a kind of reagent commonly used in medical and biological fields to prevent blood coagulation. Among them, pig heparin and heparin sodium are very common in the market. Although they appear similar on the surface, there are certain differences in structure, source, characteristics, and application. Below, we will compare and analyze pig heparin and heparin sodium to help you further understand the differences between the two.   1、 Structure and Source   Hoggarin is a natural polysaccharide Anticoagulant, which is mainly extracted from pig intestinal mucosa. Its main component is a mixture of heparin sulfate and other sulfate polysaccharides. Heparin sodium is a synthetic Anticoagulant, and its structure is similar to natural heparin. But its preparation is generally achieved by extracting heparin from animal (such as pig) mucosa, and then chemically modifying and refining it.   2、 Molecular weight and properties   The molecular weight of pig heparin is relatively large, usually ranging from 3000 to 30000 Daltons. It has anticoagulant activity and can inhibit coagulation reactions by forming complexes with coagulation factors and antithrombin. However, the molecular weight of heparin sodium is relatively small, usually around 15000 Daltons. However, it also has anticoagulant activity, usually by forming a complex with thrombin to block the coagulation process.   3、 Anticoagulant mechanism   Porcine heparin blocks the activity of thrombin by binding to thrombin and coagulation factor Xa, thereby inhibiting blood coagulation. Heparin sodium plays an anticoagulant role mainly by combining with thrombin and antithrombin III (AT-III). It can improve the anticoagulant activity of AT-III and inhibit the formation of thrombin.   4、 Application field Porcine heparin is mainly used in cardiovascular surgery, dialysis treatment, and the prevention and treatment of thrombotic diseases. It is also used as a Anticoagulant in laboratory research. Heparin sodium is usually used as extracorporeal blood Anticoagulant in blood collection vessels, and is suitable for liver and kidney function testing, blood glucose and routine biochemical testing.   Although both porcine heparin and heparin sodium are Anticoagulant, they are different in structure, source, characteristics and application. The choice of anticoagulant to use should be based on actual needs, and attention should be paid to the amount used during the use process. Excessive or insufficient use can have an impact on the experimental results. As a professional supplier of heparin sodium, Desheng produces products with analytical purity, which can be added to test tubes for use as extracorporeal blood Anticoagulant.

Crude heparin sodium CAS number and purpose   Heparin, as a naturally occurring substance, is mostly prepared into heparin sodium and used in medicine. However, in reality, it has many uses in addition to medicine, such as biochemical testing, blood collection and processing, or cosmetics. Most of the heparin sodium in these fields is purified and processed from crude heparin sodium to make high-quality heparin sodium for use. Below, we will focus on introducing crude heparin sodium to everyone.   heparin sodium powder     Crude heparin sodium CAS number   Firstly, let's understand what CAS number is. CAS number is a unique identifier for a chemical substance, assigned and managed by the International Chemical Registry (IUPAC). The CAS number is composed of numbers, representing the structure and composition of a compound, and can be used to identify and locate the compound globally. The CAS number of crude heparin sodium is 9041-08-1, which represents its composition and structure. As a mucopolysaccharide containing sulfate groups, it has strong negative charge biological activity and can be purified to prevent blood clotting.   Preparation of crude heparin sodium   1. Wash the fresh pig intestines (or naturally thawed pig intestines) with clean water to remove any debris, and then perform enzymatic hydrolysis.   2. Stir thoroughly, adjust the pH value with a small amount of alkaline solution, and maintain the solution temperature at 37-40 degrees Celsius to continue enzymatic hydrolysis for 3-4 hours.   3. Add a certain weight of refined salt, thoroughly mix it, and then heat it up for about 30 minutes. Fine filter and adjust the filtrate back to its pH range of 9.0-9.5 for ion exchange adsorption treatment.   4. After elution and filtration, combine the clear solution and filtrate, adjust the pH value again to an accuracy of 6.0-6.5, add measured ethanol to precipitate overnight, and carefully dry and suck out the upper clear solution, collect the lower sediment, and filter until dry. After vacuum drying, crude heparin sodium is prepared.   The use of crude heparin sodium   Usually, crude heparin sodium is used as the raw material for cosmetics. Due to its low production requirements and impurities, it is rarely used in the market, and its use is far less extensive and effective than high-quality heparin sodium. For example, refined heparin sodium can be added to the blood collection tube for use as an external Anticoagulant, or it can be prepared into an injection drug for use in the treatment of thrombotic diseases. The refined heparin sodium extracted from crude heparin sodium has high main content and few impurities, so it is more valued.   As a professional supplier of heparin sodium, Desheng's products are analytical pure, which are mainly used as Anticoagulant in blood collection vessels, with stable performance.
