Bovine calf serum is a cost-effective alternative to Fetal Bovine Serum (FBS). It is often used with robust cell lines when large quantities of serum are needed such as in the manufacturing of biological drugs and vaccines. Bovine calf serum is derived from calves that are generally less than 22 weeks old. It has very high levels of transferrin, which allows for iron fortification to levels of more than three times greater than normal FBS. Iron is essential for cell respiration and metabolism and for some cell lines, makes up for the lower levels of growth factors and other metabolites found in calf serum when compared to FBS.
Using industry leading techniques, blood is aseptically collected at abattoirs, centrifuged to isolate the serum and immediately frozen for testing and further processing. The raw sera is then true pooled and is triple 0.1 micron sterile filtered with a Sterility Assurance Level (SAL) of 10-3. Every lot then must pass USP <71> and EP 2.6.1 sterility testing, growth promotion testing, as well as test negative for mycoplasma and number of industry-monitored viruses. Additional testing includes endotoxin, hemoglobin, pH, osmolality, total protein, and a biochemical profile that contains various metals, proteins, hormones, and other metabolites.
