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 0,1 µm.

• pH specification: 7,4 ±0,6

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

Those Mixed FBS will contain sera coming from the same continent and imported into Europe according to the European regulation. Those Mixed FBS will be produced according to the same Biowest procedures and will respect the same quality standard than usual Biowest FBS.
