Heparin, as an important anticoagulant, plays an indispensable role in medical and laboratory applications. Its anticoagulant effect is strong, and heparin sodium and heparin lithium, as common binding forms, have unique advantages, making them one of the highly respected choices in blood collection additives.   1、 Heparin anticoagulant effect   Heparin plays a significant role in anticoagulation, starting from enhancing the affinity between antithrombin 3 and thrombin, accelerating the inactivation of thrombin, and inhibiting platelet adhesion and aggregation. It can enhance the activity of protein C and stimulate the release of anticoagulant and fibrinolytic substances from vascular endothelial cells. Heparin exhibits multiple anticoagulant properties, and both heparin sodium and heparin lithium possess these anticoagulant properties.   2、 Clinical application of heparin sodium and heparin lithium   Heparin sodium and heparin lithium are important substances in anticoagulant blood vessels, and processed blood samples can be used to measure pH and electrolytes. At the same time, due to the addition of heparin, the anticoagulant enzyme in the blood collection vessel prolongs the clotting time of the sample, and is also suitable for projects such as red blood cell fragility test, blood gas analysis, red blood cell compression test, erythrocyte sedimentation rate and universal biochemical determination. However, it should be noted that heparin is not suitable for blood coagulation experiments, as excessive heparin can cause significant changes in white blood cells and interfere with accurate counting.   3、 Selection of heparin sodium and heparin lithium   The two common binding forms of heparin, heparin sodium and heparin lithium, may be confusing in their selection. Although they are all binding forms of heparin, there are significant differences in their effective ion binding, resulting in significant differences in the degree of dissociation. Although experimental comparisons have shown that heparin lithium is slightly better than heparin sodium in terms of efficacy, the dosage used in vacuum blood collection also varies. But in fact, their use is based on experimental requirements, and their anticoagulant effects are consistent, and they can both exert stable performance in clinical practice.   So from the above, it can be seen that the heparin sodium and heparin lithium in the additive for blood collection are both good and play irreplaceable roles in medical diagnosis and laboratory testing. Their advantages make them the preferred choice in many medical and laboratory fields. As an advantageous supplier of heparin sodium and heparin lithium, Desheng can provide raw material powders with low impurities and excellent anticoagulant effects, which are ready to use and convenient for storage and transportation at a competitive price.

Heparin sodium, as a commonly used anticoagulant for blood collection, plays an important role in medical and laboratory research. However, some key issues need to be noted when using heparin sodium to ensure its effectiveness and safety. Let's take a look at the issues to pay attention to when using heparin sodium.   1. Selection of dosage: The dosage of heparin sodium should be determined based on the specific situation and purpose. Different biochemical projects may require different levels of heparin sodium. For example, the recommended dose range for conventional test tubes is 12-30IU of heparin sodium per milliliter of blood, and the anticoagulation of micro blood collectors can be less than 14IU per milliliter of blood. Therefore, suitable heparin sodium test tubes should be selected for blood collection based on the examination items before use.   2. Preparation and storage: Heparin sodium is generally supplied in the form of raw powder, and appropriate preparation and dissolution are required before use. Generally, deionized water can be used for dissolution. It is important to follow the recommendations in the product manual during the preparation process to ensure that the concentration of dissolved heparin sodium meets experimental or clinical requirements. The prepared heparin sodium solution should be added in a timely manner. If it needs to be placed, it should be stored in a sterile environment at 0-4 ℃ as much as possible. The addition should be completed within a week, avoiding direct sunlight to maintain its stability.   3. Addition method: Generally, the addition method is divided into machine and manual methods. Regardless of which method is used, attention should be paid to completing it in a sterile state. If using a machine, it is necessary to clean its conveying pipeline and container, and disinfect and air dry it with alcohol to ensure that there are no impurities, bacteria, or scale attached to the pipe wall.   4. Inverted mixing: To ensure sufficient anticoagulation effect on blood, the test tube should be inverted and mixed as soon as possible after blood collection, especially when the temperature of the blood collection environment is too high. If not inverted in a timely manner, it may cause abnormal test results.   5. Timely testing: Pay attention to completing the test within 6 hours, as heparin is a non irreversible anticoagulant. If the test is not completed within the specified time, it is prone to result errors.   In summary, as an important anticoagulant for blood collection, heparin sodium needs to be used with caution and follow professional advice. Reasonable dosage and correct usage methods will help ensure the effectiveness and safety of heparin sodium, thus providing reliable support for clinical and laboratory research.   As a supplier of heparin sodium raw materials, Desheng not only provides high-quality products, but also can customize production according to customers' specific needs to meet the requirements of different experiments, while paying attention to providing comprehensive after-sales service.

Heparin Sodium is a commonly used anticoagulant widely used in clinical medicine and laboratory research. It can not only be prepared into drugs to prevent the formation of blood clots, but also effectively inhibit blood coagulation in blood collection vessels. Blood samples treated with anticoagulation are suitable for various biochemical items. However, in addition to synthetic heparin sodium, there is also a natural source of heparin sodium, which is extracted from pigs. This article will introduce the characteristics and preparation process of heparin sodium extracted from pigs.   characteristic   The heparin sodium extracted from pigs is extracted from the intestinal mucosa of pigs. Compared with synthetic heparin sodium, it has the characteristics of naturalness and diversity. In the early stage, heparin was extracted from animal livers, but it was later discovered to exist in the small intestine of pigs. In addition, China's pig farming industry is developed, and it is naturally obtained from pig intestines, which is a natural source of anticoagulants. This also makes it more popular in certain specific application fields. Diversity indicates that there may be slight structural differences in heparin sodium from different sources, which may lead to different biological activities and bioavailability of heparin sodium extracted from pigs in certain situatio.   Preparation process   The preparation process of heparin sodium extracted from pigs involves multiple steps and techniques to ensure the production of high-purity heparin sodium products. The approximate steps are as follows:   1. Raw material processing: Firstly, extract the precursor substance of heparin sodium from fresh small intestine. After careful cleaning of the small intestine, the mucosa is scraped off and crushed into fragments, preparing for the subsequent steps.   2. Heating enzymatic hydrolysis: The chymosis mucosa is placed in a heating tank, with an appropriate amount of water added, followed by approximately 8% trypsin. Next, by gradually adding a weak alkaline solution, the pH of the solution is maintained between 8 and 10. The temperature gradually increases, first heating to 30-40 ℃, holding at this temperature for 2-3 hours, then heating to 50-60 ℃, holding for 10-20 minutes. The entire process requires maintaining the pH of the solution between 8.5 and 9.5.   3. Cooling adsorption: The solution after enzymatic hydrolysis is cooled to 30-40 ℃ and the surface oil is removed. Then, add the resin to the solution and stir for 6-7 hours to achieve the adsorption of heparin sodium. After adsorption, the resin is filtered out, carrying heparin sodium.   4. Elution: By adding a 10% mass fraction of sodium chloride solution, the adsorbents on the resin are eluted. This process is carried out at 50-55 ℃ and stirred continuously for 3-4 hours to ensure complete elution of heparin sodium from the resin. This step was repeated twice, and the two eluents were merged.   5. Sedimentation: The combined eluent is filtered and transferred to the sedimentation tank. Adjust the pH of the solution to 7-8 while adding 80-85% alcohol. Next, the solution is sealed for 10-12 hours to promote the formation of heparin sodium precipitate, which is then filtered out.   6. Dehydration and drying: The filtered sediment is placed in a drying oven for dehydration and drying. After this step, a high-purity pig extracted heparin sodium product was ultimately obtained.   Through the above preparation process, heparin sodium extracted from pigs was successfully prepared, and each step in this process requires strict control of conditions to ensure the final product quality. As a manufacturer of heparin sodium, Desheng can provide high content raw material powder, which is convenient and simple to use. When added to blood vessels for in vitro anticoagulation, its performance is stable. If you are interested, please feel free to contact us at any time!

Blood collection is a common operation in clinical diagnosis and laboratory testing. To ensure that the collected blood samples accurately reflect the biochemical status of the body, appropriate anticoagulants need to be used to prevent blood coagulation. Heparin lithium, as a commonly used anticoagulant for blood collection, is widely used in clinical and laboratory settings. Below, we will explore the usage and precautions of heparin lithium as an anticoagulant for blood collection. Let's take a look together.   The mechanism of action of heparin lithium   Heparin lithium is a natural polysaccharide that primarily inhibits the activity of thrombin, thereby preventing the coagulation process. It can bind to antithrombin III, thereby inhibiting the formation of thrombin and inhibiting the coagulation cascade reaction. At the same time, it can also inhibit platelet aggregation by binding to coagulation factors on the surface of platelets.   Method of using heparin lithium as an anticoagulant for blood collection   Heparin lithium is usually injected into the blood collection vessel in the form of a solution to come into contact with the blood and achieve anticoagulant effects. When using heparin lithium, the following aspects need to be noted:   1. Appropriate concentration: The concentration of heparin lithium needs to be determined based on specific circumstances. Usually, in medical practice, the appropriate concentration of heparin lithium is determined based on the size of the blood collection vessel and the amount of blood required to be collected. The recommended amount for general industry standards is 9.4IU-28IU of heparin lithium per milliliter of blood. If using a peripheral blood sampler, anticoagulation needs to be less than 14IU per milliliter of blood.   2. Uniform mixing: Before using heparin lithium solution, it is necessary to thoroughly mix it evenly to ensure that heparin lithium is evenly distributed in the solution and ensure its anticoagulant effect is consistent.   3. Adding technique: When adding and preparing heparin lithium solution, it is generally divided into manual and machine adding. Machine adding requires setting machine parameters and paying attention to cleaning the pipeline to avoid impurities or bacterial residues. At the same time, it is necessary to timely check whether the dosage of the addition meets the requirements to ensure that the anticoagulant effect reaches the ideal state.   Matters needing attention   1. To ensure sufficient anticoagulation of blood samples, medical staff should invert and mix them as soon as possible after blood collection, without using excessive force, just gently invert 5 to 8 times.   2. The heparin lithium anticoagulant tube should be tested within 6 hours as much as possible, as it is a non irreversible anticoagulant. If not tested for a long time, it may lead to deviation in the test results.   3. Heparin is sensitive to indicators such as AST, ALT, and TBIL. It can participate in the metabolism of cellular enzymes and ions, and its usage may affect the detection results. Therefore, it is important to pay attention to the amount of heparin lithium tubes added during the detection project and select appropriate heparin lithium tubes according to different projects.   As an additive for blood collection, heparin lithium can effectively prevent blood coagulation during the blood collection process by inhibiting thrombin activity and reducing platelet aggregation, ensuring the quality of collected blood samples. Through scientific and reasonable use, heparin lithium will better exert its anticoagulant effect during blood collection, ensuring the accuracy of clinical diagnosis and laboratory testing.   As a manufacturer of heparin lithium, Desheng can provide raw material powder for manufacturers to prepare and add, with high main content and stable performance. 80% of test tube manufacturers will choose to cooperate with us.

Heparin sodium, as a commonly used Anticoagulant in clinic, can not only be added to blood collection vessels to prevent blood coagulation, but also can be used as a drug to effectively prevent thrombosis and reduce the incidence of cardiovascular and cerebrovascular diseases. According to different preparation methods and structural characteristics, heparin sodium can be divided into various types. Next, we will introduce the classification of heparin sodium in detail.   Classification according to preparation method   1. Natural heparin sodium: a Natural product mainly extracted from pig intestines, bovine lungs and other animal viscera. After complete extraction of heparin, it is refined to obtain heparin sodium with high purity. Its production requirements are strict, and it is usually added to the blood collection vessel for use, with relatively stable performance.   2. Synthetic heparin sodium: obtained through chemical synthesis, it has high yield and cost advantages. Currently, polymer method and metal organic compound method are mainly used in the market for synthesis, and its performance and usage are far inferior to the first naturally prepared heparin sodium.   Classification based on structural features   1. Ordinary heparin sodium: Ordinary heparin sodium is a high molecular weight heparin containing multiple repeating units, appearing in the form of a drug. Its anticoagulant effect is good, but its bioavailability is low, and it is prone to side effects. It is rarely used in clinical practice.   2. Low molecular weight heparin sodium: Low molecular weight heparin sodium is a short chain heparin obtained through chemical modification, with high bioavailability and suitable for intravenous injection. Due to its direct contact with the human body, it not only requires high production requirements and expensive prices, but also requires obtaining corresponding certificates before production, and is subject to the supervision of the Medical Commission.   3. Heparin sodium salt: it is a kind of raw material heparin sodium, which is mainly extracted from pig intestinal mucosa, and then obtained through ion exchange adsorption. Its average molecular weight is about 15000, and its potency is between 150IU-180IU. It is generally of non injection grade. It is prepared into a solution and added to the blood collection vessel as an in vitro Anticoagulant.   Classified by purpose   1. Medical heparin sodium: medical heparin sodium includes medical heparin sodium and extracorporeal Anticoagulant heparin sodium, which are mainly used in cardiac surgery, hemodialysis, vascular interventional therapy and other fields, with strong anticoagulant effect and therapeutic effect. While the external Anticoagulant heparin sodium is used clinically, the main purpose is to help blood coagulate quickly in blood collection and improve the inspection efficiency of medical staff.   2. Industrial heparin sodium: This type of heparin sodium is generally low in purity, contains impurities, has low production requirements, and is cheap. It is mainly used in the manufacturing of industrial products such as cellulose and paper.   Different types of heparin sodium have different characteristics and application ranges, and selecting the appropriate type of heparin sodium needs to be considered based on the specific usage.

Heparin sodium is an important chemical reagent that can be widely used as an additive for blood collection in clinical medicine, and also has a certain role in scientific research. The high level of its popularity represents market demand, which inevitably varies in price and is affected by various factors, such as production process, price, and manufacturer scale. Let's take a look at the factors that affect the price of heparin sodium per kilogram?   1. Production process: Heparin sodium is a reagent obtained by fine extraction and purification of natural heparin. Its production process is complex and requires advanced technology and equipment. The high investment in equipment increases costs, and the price of heparin sodium will also be affected.   2. Raw material cost: Its production requires a large amount of raw materials, including heparin from animals (such as pig intestinal mucosa). However, incomplete statistics are required. Only 3000 pigs can extract 1kg of heparin. If the number of live pigs is small, it is also an important factor affecting the price of heparin sodium.   3. Production scale: Production scale is another important factor affecting the price of heparin sodium. Mass production can reduce the production cost per unit product, thereby lowering the price of the product. Therefore, generally larger manufacturers are able to provide more competitive prices.   4. Market competition: As a commonly used Anticoagulant, the market competition is fierce, and the competition between different manufacturers will also affect the product price. In a highly competitive market, manufacturers may lower product prices to compete for market share.   5. Quality certification and standards: As a clinical reagent, heparin sodium must comply with strict quality certification and standards. Products that have passed quality certification and compliance standards are usually priced higher, but their quality and safety are also more guaranteed.   As an important Anticoagulant, heparin sodium is widely used in clinical medicine and scientific research.

Nowadays, with the improvement of living standards, people are paying more and more attention to their physical health status, and the demand for physical examinations is also increasing. During a physical examination, blood analysis is a necessary item to be checked. When carefully observing the blood collection vessels, it can be observed that each type of blood collection vessel cap has a different color. This is because different reagents are added to tubes of different colors, such as blood collection tubes with Anticoagulant, coagulant and no reagent.   At present, the widely used reagent is Ethylenediaminetetraacetic acid dipotassium salt, which is one of the Anticoagulant and can prevent blood coagulation. However, the basis for its effectiveness depends on performance, such as molecular weight, pH value, solubility, or main content. So next, let's introduce this aspect to everyone.   Properties of dipotassium Ethylenediaminetetraacetic acid   Its appearance is white crystalline powder, without a pungent odor, and is easily soluble in water. As the finished product is a powder, it is easy to absorb moisture, with an average molecular weight of 404.6 and a pH value of 4.8 ± 1 in a 5% aqueous solution. The solubility in water is ≥ 60%, and it is of analytical purity grade, with a main content of over 99%. Adding it as a solution to a test tube has strong stability and can effectively protect blood components from damage.   Anticoagulant mechanism of dipotassium salt of Ethylenediaminetetraacetic acid   Because it needs to be prepared into a solution when added to a vacuum test tube, Ethylenediaminetetraacetic acid and Ethylenediaminetetraacetic acid anions can be dissociated on this basis. They can effectively chelate calcium ions in the blood, control calcium ion reaction from the source, prevent internal and external coagulation process, so as to achieve the purpose of blood coagulation and inhibit platelet aggregation. At the same time, compared with other anticoagulants of the same type, Ethylenediaminetetraacetic acid dipotassium has the smallest effect on blood cell composition and high solubility, so it is also a rational Anticoagulant that is highly respected in medicine.   Determination of pH value, main content, and solubility   In addition to the molecular weight that can represent the overall mass of Ethylenediaminetetraacetic acid dipotassium salt, the pH value, main content and solubility are also important. The measurement method is as follows:   1. Determination of main content: weigh an appropriate amount of sample, add water and ammonium chloride solution to fully stir and dissolve, then add an appropriate amount of Eriochrome Black T indicator, titrate with Zinc chloride standard titration solution until the solution turns red and purple, and then calculate the content according to the calculation formula. Desheng Ethylenediaminetetraacetic acid dipotassium salt is a dihydrate, so the main content may be higher than 100, which is normal.   2. PH measurement: Dissolve an appropriate amount of the sample to be tested in pure water, stir at room temperature for about 5 minutes, and then use a pH meter to measure it.   3. Solubility measurement: Take an appropriate amount of the sample to be tested and dissolve it in pure water. Stir at room temperature for 5-10 minutes to observe if it is completely dissolved.   As a superior supplier of Ethylenediaminetetraacetic acid dipotassium salt, Desheng has not only high purity and stable performance, but also independent production lines and large warehouses for spot sale.
