RMBIO produces US origin iron supplemented and heat inactivated calf serum for use in cell culture media. Supplementing iron to calf serum can enhance serum transferrin levels and in many cases be a much less expensive alternative to FBS in promoting cell growth and its effectiveness. Heat inactivation helps protect against growth inhibiting immune factors like serum complement that may be present in the serum.

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 calf serum by raising the temperature of the serum to 56°C in a water bath and strictly maintaining the condition for 30 minutes.
