Fetal Bovine Serum, Heat Inactivated, US Origin, 50 mL

Fetal Bovine Serum, Heat Inactivated, US Origin 50 mL. RMBIO FBS (Fetal Calf Serum) is sourced from USDA-approved suppliers within the U.S. and is processed in our cGMP-compliant, ISIA traceability certified, and FDA-registered facility. RMBIO FBS (Fetal Calf Serum) is processed under strict protocols that ensure sterility, high quality, and excellent growth-promotion and performance over a range of applications and cell lines. The average endotoxin level is < 1 EU/mL, the average hemoglobin level is < 15 mg/dL, and the total protein specification is 3.0-4.5 g/dL. RMBIO heat inactivates FBS by raising the temperature of the serum to 56°C in a water bath and strictly maintaining the condition for 30 minutes. 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. All lots of FBS are triple 0.1 um sterile filtered and 9CFR-tested. Product should be stored at ± -10° C.
