FBS blocks reactive oxygen species generation, which otherwise is not eliminated in serum-free media (SFM) systems. It also protects cells from oxidative damage and apoptosis.

Fetal bovine serum is the main component present in almost all media used for the culture of animal cells. It provides serum additives to the cell culture medium, which is essential for supporting growth of a variety of cell types. It is rich in growth factors and protein but low in γ-globulin content.

FBS sourced from Canada is used in a broad range of cell culture applications. FBS provides many non-defined growth promoting and survival enhancing factors to cells in culture. It was used as a supplement for different cell cultures.
