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

Fetal Bovine serum 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.

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