Fetal Bovine Serum (FBS) is the liquid part of the blood depleted of the cellular fraction and coagulation factors. It is extracted after centrifugation of coagulated fetal bovine blood collected aseptically. Sterile FBS is obtained by triple filtration of 0.1µm.

FBS contains proteins and growth factors allowing maintenance and proliferation of eukaryote cells in vitro. It also contains attachment factors that create a “coating” effect on the plastic of the support, thus increasing cell adhesion. It is an essential product in cell culture because of the different components it provides.

Heat treatment allows to inactivate the complement acting in the immune system to avoid an interference with some experimentation, in particular the tests of immunology. It allows also to inactivate viruses and to eliminate some bacterial contaminants such as the mycoplasma.

All FBS batches are tested for endotoxin and mycoplasma levels, specific viruses testing (BVD), hemoglobin and total protein rates and cell culture performance.
