Biosera FBS is derived from blood, collected aseptically using a closed sterile bag system. The blood is immediately centrifuged and the serum frozen for transfer to Biosera’s processing facilities. Biosera vigorously tests serum for sterility, mycoplasma, specific viruses and the ability to support cell growth. Certified and special certified sera are subject to a battery of further tests including chemical components, protein electrophoresis and radial immunodiffusion. All batches of FBS have full recorded traceability.

Other sera types, synthetic culture media, salt solutions and buffers, antibiotics, vitamins, amino acids are also available from Biosera.
