35-057-CF, Corning® Clever Calf Serum, 50 mL, United States Origin

Clever Calf Serum is an engineering calf serum alternative to Fetal Bovine Serum that contains proprietary growth supplements to stimulate cell growth and proliferation with a broad range of cell types. It contains a lower cost serum that is abundant in supply ensuring constant availability. Clever Calf Serum is designed specifically to replace FBS and can be used in the same concentrations.. Sera Processing 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. Authenticity of the serum is verified using industry leading measurements of Gamma-Glutamyl Transferase and Corning’s high internal standard of ≤ 10 IU/L. Additional testing includes endotoxin, hemoglobin, pH, osmolality, total protein, and a biochemical profile that contains various metals, proteins, hormones and other metabolites. United States Origin
