Fetal Bovine Serum (FBS) is the liquid part of blood that remains after removing the cellular fraction and coagulation factors. It is extracted by centrifuging aseptically collected, coagulated fetal bovine blood. Sterile FBS is achieved through triple filtration at 0.1µm.
FBS contains proteins and growth factors that support the maintenance and proliferation of eukaryotic cells in vitro. It also includes attachment factors that create a “coating” effect on plastic surfaces, enhancing cell adhesion. These components make FBS essential in cell culture.
Heat treatment is used to inactivate the complement system, which could interfere with certain experiments, especially in immunological testing. This process also inactivates viruses and eliminates bacterial contaminants, such as mycoplasma.
All FBS batches are tested for endotoxin and mycoplasma levels, specific viruses (BVD), hemoglobin, total protein content, and cell culture performance.
