Corning™ Fetal Bovine Serum, Premium (Tetracycline Negative)

Fetal Bovine Serum often contains the antibiotic tetracycline (tet) and researchers using very sensitive tet-inducible gene expression systems encounter problems with unintended expression as a result. Serum containing minimal levels of tetracycline is needed to ensure accurate gene expression.

Fetal Bovine Serum (FBS) is a time tested, universal supplement used in cell culture. It provides many compounds that have been shown to satisfy specific metabolic requirements for the culture of cells, including hormones, growth factors, cell attachment factors, pH buffer, protease inhibitors, vitamins, minerals, lipids, and a variety of undefined components. Serum also protects against toxic effects associated with pH change, the presence of heavy metal ions, endotoxin, and proteolytic activity.

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.
