New Born Calf Serum is processed from calves that are 3-10 days old. It contains higher levels of proteins and immunoglobulins and less growth factors than Fetal Bovine Serum (FBS). It is a cost effective alternative to FBS and can be used for culturing most mammalian cell lines. It has proved to be an efficient growth promoter in 3T3 cells (mouse fibroblasts).
