Central America or Mexico Origin (United States Department of Agriculture) tested Fetal Bovine Serum (FBS) is collected under partnership with a leading global supplier of raw FBS. USDA FBS are collected in countries free from BSE and FMD as determined by the USDA. USDA FBS is aseptically processed by J R Scientific and placed in quarantine. Samples are provided to the USDA for safety testing. The FBS sample submitted to the USDA is inoculated into 3 sheep by the subcutaneous route. Serum from the sheep is tested for antibodies against Bluetongue Virus by agar gel immunodiffusion and for Akabane disease by the serum neutralization test on the day of inoculation and at 28 days post inoculation. Upon a satisfactory USDA report the FBS is released for distribution.
