Product Details

IgG is the most abundant antibody in FBS. The average level of IgG in normal fetal calf serum is approximately 70-300 µg/mL. 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.

  • 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
  • All fetal bovine serum is fully traceable and is sourced from audited suppliers
  • Storage conditions: ≤ -10° C
