Product description:

Omega Scientific’s U.S. Source Fetal Bovine Sera is collected entirely from USDA licensed abattoirs and processed within the United States. Our serum is maintained at or below 40°F from collection through sterile bottling to ensure superior performance. Processed serum is thawed and then heated in a water bath at 56°C for 30 minutes. The serum is swirled every 10 minutes to ensure proper integration of concentrated protein. The “heat” inactivates the “complement” in the serum. Complement is defined as a series of 20 proteins produced by the liver which amplify the action of antibodies.
