We offer many varieties of bovine serum (cow), chicken, caprine (goat), equine (horse), human, ovine (sheep), porcine (pig) and rabbit sera produced and tested for use in cell culture applications. Our sera are tested for viral contaminations and cell culture performance, and supported with certifications of origin. Sigma-Aldrich has 30+ years of experience in the management and production of sera for use in cell culture. We manage and segregate our adult, newborn and fetal bovine sera (FBS) inventories by country and/or region of origin to meet United States and international regulatory standards and restrictions. We segregate our FBS into USA sourced and non-USA source sera. Our non-USA sourced FBS is lot designated and managed as non-USA USDA approved or country/region of origin/restricted sales. We offer lot testing and matching of our FBS.
