Heat Inactivation 101
Heat inactivation is an industry standard treatment that helps protect against growth inhibiting immune factors like serum complement that may be present in the serum. Serum complement can have undesirable impacts on immunological endpoints like detection of neutralizing antibodies, or on the proliferation of viruses. RMBIO manufactures heat inactivated bovine serum by raising the temperature of the serum to 56°C in a water bath and strictly maintaining the condition for 30 minutes.
