Of all the different types of animal serum available, Foetal (Fetal) Bovine Serum (FBS) is the most widely used basal media supplement for in vitro cell culture. FBS is particularly suitable since it contains a very low level of antibodies. Those low levels of antibodies combine with a higher concentration of growth factors than compared with adult or newborn bovine sera. This means that FBS is effective in promoting and sustaining the growth of both mammalian and insect cells.

In order to remove small molecules such as glucose, salts, hormones, cytokines, amino acids and also antibiotics, the chilled serum is dialysed from 10kDa up to 30,000kDa. This processing method is useful for receptor studies and radiolabelling assays. However, dialysis does not remove serum-bound hormones and it can reduce the growth promotion capabilities of the serum.
