Fetal bovine serum is a trait with a light yellow appearance and clear, no hemolysis, no foreign body slightly mucus. Fetal bovine serum should be taken from caesarean sectioned cattle; new bovine serum from new cattle within 24 hours of birth; calf serum from calves 10-30 days after birth.

Fetal bovine serum is of high quality, because fetal bovine has not yet been exposed to the outside world, and the antibodies, complement and other components contained in the serum that are harmful to cells are at least harmful.

Fetal bovine serum good quality good quality?

Fetal bovine serum is mainly through appearance (transparent and clear), total protein content (fetal bovine serum generally ranges from 30-40mg/ml), hemoglobin (not higher than 20mg/dl), PH (domestic serum, more than 7.5, imported fetal bovine serum, more than 7.5), microorganisms, immunoglobulin (imported fetal bovine serum, does not contain IgM, IgG content is also low), antibiotic content, etc.

Effects of fetal bovine serum:

Fetal bovine serums are included in:

1. Provide hormones for maintaining cellular exponential growth, no or small amount of nutrients in the basal medium and major low molecular weight nutrients.

2. Provide binding proteins that can recognize vitamins, lipids, metals and other hormones, and be able to bind or regulate their material viability.

3. In some cases, proteins can be combined with toxic metals and pyrogens to detoxify.

4. It is a source of factors required for plastic culture media, spread with cell adherents.

5. It plays the role of acid-base buffer.

6. Provide protease inhibitors to inactivate the remaining trypsin as the cells are passed from generation to generation, protecting the cells from damage.

Fetal bovine serum is used for mammalian cell culture; therefore, fetal bovine serum is widely used. For example, fetal bovine serum can be used for scientific research, industrial production, human-veterinary vaccine production and quality control of biotechnological drugs.

Fetal bovine serum is a natural medium commonly used in laboratories. It is nutrient-rich, but it is also prone to carrying viruses due to viral infections in cows, potentially interfering with cell culture. Therefore, it is not only necessary to ensure the health of pregnant cows from the source, but also to ensure the quality of fetal cow serum in government-registered slaughterhouses.
