fetal bovine serum components

Hey. It’s not very clear what you wanted to say. There are no questions, but some links to sites. I know that the serum is a liquid fraction of the condensed blood from the fetal calf, depleted of cells, fibrin and clotting factors, but contains a large number of food and macromolecular factors necessary for cell growth. Bovine serum albumin is the main component of fetal bovine serum. Fetal bovine serum also contains small molecules such as amino acids, sugars, lipids and hormones.
FBS is used in the cell culture of eukaryotic cells and has a wide range of applications. For example, it is used in research, production and control of vaccines for people and veterinarians and biotechnological preparations.
If you are interested in the question Why is fetal serum used against, for example, a newborn serum or an adult serum?
I can say that fetal serum contains more growth factors and has a low content of gamma globulin (immunoglobulin). In addition, fetal serum contains lower levels of supplements than in adults or newborns. Additions have an undesirable effect of lysing cells in culture and interfere with immunological assays. There is a difference between serum and plasma
Serum is prepared after blood coagulation, while plasma contains anticoagulants and thus preserves protein involved in the coagulation cascade. Thus, fibrin and proteins associated with fibrin are absent in the serum.

The main countries of cattle are the main suppliers of fetal bovine serum. Countries include the United States, Australia, New Zealand, Canada, South and Central America.

Production and collection of whey products are regulated by government agencies.

I think this is enough to understand the term itself and its effect.
