What Are Serum Components?
Serum refers to the light yellow transparent liquid that is separated after removing fibrinogen and certain coagulation factors from the blood after blood coagulation, or refers to the plasma in which fibrinogen has been removed. Its main role is to provide basic nutrients, provide hormones and various growth factors, provide binding proteins, provide pro-exposure and growth factors to protect cells from mechanical damage, and play a role in protecting cells in culture.
- Serum refers to a gelatinous liquid after plasma has been removed from fibrinogen. Each 100ml of human serum contains 6-8g of protein, mainly albumin and globulin. The serum does not clot. It has the functions of immunity, maintaining acid-base balance and osmotic pressure, and serum protein can also be used for reserves when the body's protein is insufficient. Human and animal sera are commonly used to perform various serological tests to help diagnose the disease. Antibody-containing serum can be used for the prevention or treatment of diseases. [1]
- Serum is removed from plasma
- Provide basic nutrients:
- serum
- Light yellow transparent liquid precipitated by blood coagulation [2]
- The preservation of serum should pay attention to the following points:
- (1) Serum that needs to be stored for a long time must be stored in a low temperature refrigerator at -20 ° C to 70 ° C. Do not store in a refrigerator at 4 for more than 1 month. Because the volume of the serum will increase by about 10% when it freezes, the serum must be reserved for a certain volume of space before freezing into the low-temperature refrigerator. Otherwise, contamination or freezing of the glass bottles are prone to occur. crack.
- (2) Heat inactivation refers to the serum that has been completely thawed at 56 ° C for 30 minutes. During the heating process, it should be shaken regularly. The purpose of this heat treatment is to inactivate complement in serum. Unless necessary, this heat treatment is generally not recommended, because heat treatment will cause a significant increase in serum sediments, and it will also affect serum. the quality of,
- Depending on the type of bacteria or virus injected, and different types of animals, antiviral serums with different immune properties are obtained. According to the market research of Henan Shunxin Animal Blood Products Co., Ltd., the animal anti-toxin serum in the market is roughly divided into the following types:
- 1. Swine antisera: swine fever antisera, pig blue ear antisera, porcine circovirus antisera, porcine pseudorabies antisera, porcine parvovirus antisera, swine foot and mouth disease antisera, swine flu Antiviral serum and so on.
- 2. Avian antiviral serum: goose fever antiviral serum, duck liver antibody antiviral serum, duck serositis antiviral serum, avian influenza antiviral serum, Newcastle disease blood antitoxic serum, etc.
- 3. Bovine anti-toxin serum: anti-foot-and-mouth disease anti-serum, cow mastitis anti-serum, bovine epidemic anti-serum, bovine viral diarrhea anti-serum, bovine hemorrhagic sepsis anti-serum, etc.
- 4. Sheep anti-serum: sheep pox anti-serum, sheep foot-and-mouth disease anti-serum, sheep ruminant animal epidemic anti-serum, sheep epidemic anti-serum, sheep enterotox anti-serum, sheep sudden gangrene anti-serum Sheep black blight antiserum
- 5. Canine antiviral serum: canine rabies antiviral serum, canine distemper antiviral serum, canine parainfluenza antiviral serum, canine adenovirus antiviral serum and canine parvovirus antiviral high immunity serum, canine mink pseudorabies Antiviral serum, parvovirus antiviral serum, Japanese encephalitis antiviral serum, etc.
