Donor Horse Serum - Heat Inactivated and Gamma Irradiated Equine Serum
Equine serum can be a cost-effective alternative to fetal bovine serum for use in a variety of cell culture applications. RMBIO obtains donor horse serum from closed herds that are carefully controlled and inspected by veterinarians. Horses are regularly tested for equine infectious anemia using Coggins tests. Before collection, donor horses are fasted to ensure lower lipid levels. All lots of equine serum are 0.2µm sterile filtered and feature low hemoglobin levels.

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