Gamma Irradiation 101
Gamma irradiation is a physical inactivation approach used to achieve pathogen reduction in the serum. This mitigates risk from low-level contaminants that may not be detected through viral or mycoplasma testing. RMBIO serum is gamma irradiated via controlled exposure to Cobalt 60 at an industry standard dose of 25-40kGy. Most typical viral contaminants of bovine serum are readily inactivated at this irradiation range. Advantages of gamma irradiation include:

• No potential for residual contaminants
• Widely accepted by pharmaceutical and research industries
• Accepted by regulatory agencies
• Minimal effect on product performance
• Effective virus inactivation
