Fetal Bovine Serum Ultra-low Endotoxin

Fetal Bovine Serum 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.

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.

Endotoxins, i.e. LPS for E.Coli, are components of the walls of Gram-negative bacteria. They are released when the bacterial cell dies. Their presence can interfere with biological parameters, as cell activation. Endotoxin-low FBS is used for LPS-sensitive cell lines, as macrophage and immune cells.

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