Fetal Bovine Serum (FBS) IgG Depleted and Gamma Irradiated

Fetal Bovine Serum (FBS) IgG Depleted and Gamma Irradiated

RMBIO’s IgG Depleted FBS is manufactured using a proprietary chromatography process to meet a stringent IgG specification of < 5 µg/mL while maintaining natural cellular viability and biological growth-promotion characteristics. We then apply an industry standard gamma irradiation dose of 25-40kGy.

Product Details

RMBIO uses premium grade FBS as the starting material for our IgG Depleted FBS. We then utilize a series of chromatography procedures to reduce the IgG content. The resulting FBS has an average IgG level of less than 5 µg/mL and cell growth performance comparable to the starting material. The average level of IgG in normal fetal calf serum is approximately 70-300 µg/mL.

  • Gamma irradiated at 25-40kGy
  • Total IgG content below 5 µg/mL
  • IgG depleted FBS performs well in monoclonal antibody production
  • Triple 0.1 µm filtered
  • Large lot sizes >1000 Liters available
  • Custom packaging sizes available upon request
  • All fetal bovine serum is fully traceable and is sourced from audited suppliers
  • Storage conditions: ≤ -10° C

 

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
