FBS is the most highly used growth factor in cell culture due to its high level of nutrients. Our FBS is produced to the highest standards in order to reduce risk and product variability and to ensure product safety and performance. Our FBS is 9CFR-tested, meeting FDA and USDA requirements. Fetal bovine serum products can also be tested to meet EMEA requirements. We source our FBS cell culture medium supplement from United States (Per request, it can be sourced from Australia, New Zealand, as well as USDA approved regions in North America). These standards are built into entire supply chain. Your order is delivered exactly as you specify it. We stock a variety of grades of FBS, including charcoal treated, heat inactivated (cat#FBS001-HI), and low endotoxin levels. We can also customize to meet very specific cell culture medium supplement needs.
