Fetal Bovine Serum (FBS) is used in cell cultures to supply a rich variety of proteins including growth factors, hormones, vitamins, and other nutrients that support survival, growth, and division of cells.
Fetal Bovine Serum is the most widely used type of serum-supplement for eukaryotic cells in in-vitro cell cultures because it is considered the ideal cell growth supplement compared to other types of sera. FBS contains significantly lower levels of antibodies compared to newborn or adult sera. This minimizes the risk of reactions to antibodies for the cells growing in the culture. Furthermore, Fetal Bovine Serum’s high nutrient content and unique combination of growth factors makes FBS the most effective cell growth promoter for virtually any cell culture system.
