US Origin Fetal Bovine Serum (FBS) is the most widely used FBS in the world. Although US Origin FBS is considered the world’s standard for quality it is never the less becoming a lower standard in the view of the OIE (World Organization for Animal Health) and other regulatory bodies. On a scale of 1-4 for geographical BSE risk (GBR), with 1 being the lowest risk and 4 being the highest risk, US FBS ranks a 3 – demonstrating a moderate to high risk that BSE exists in the USA. US Origin FBS provided by J R Scientific is of the highest quality available in the USA. It is collected using state of the art aseptic collection techniques resulting in low endotoxin and hemoglobin concentrations.

J R Scientific’s proprietary disposable processing system, from pre-filtration to final aseptic dispensing, eliminates any potential for cross contamination with other products and processes.
