Fetal Bovine Serum - Charcoal/Dextran Treated, Heat Inactivated Best Seller

Pre-selected high quality Fetal Bovine Serum, also known as Fetal Calf Serum (FCS), is processed using a proprietary Charcoal/Dextran treatment proven to reduce the levels of many hormones, steroids, and other lipid-like components. Each lot produced is tested for various hormones and steroids before and after treatment to confirm the efficacy of the process. All lots of Charcoal/Dextran Treated FBS are manufactured in our ISO 9001:2015 certified facility.

Heat Inactivation - Serum is inactivated by raising the temperature to 56 °C for 30 minutes under controlled conditions. The objective of heat inactivation is to destroy complement activity in the serum without affecting the growth-promoting characteristics of the product. Removal of complement activity from the serum is not required for most cell cultures, but may be necessary for cultures that are sensitive to the complement activity. Since heat inactivation of the serum may, to some extent, decrease the growth performance properties of the serum, this procedure should only be performed if actually required for optimal cell growth. Researchers should evaluate the applicability of heat inactivation in regards to their own application. If heat inactivation is required, the process should be carefully controlled to avoid increased formation of crystalline and flocculent precipitates, gelling of serum proteins and excessive loss of growth performance. Significant damage to serum can occur when it is subjected to higher than required temperatures or heated over extended lengths of time.
