Brazilian JBS Federally Inspected Fetal Bovine Serum

摘要

Serum is the most commonly used supplement in cell culture. Fetal bovine serum (FBS) is the common choice because it contains high concentrations of growth factors and other important signaling molecules (e.g., adhesion proteins, nutrients, carrier proteins, cytokines, and hormones) required for cell survival and differentiation together with its buffering capabilities.FBS production begins with the collection of whole blood from bovine fetuses under aseptic conditions. Once collected, the blood is allowed to clot, and the serum is mechanically separated. Raw serum is kept under sterile conditions and low temperature.Further processing such as filtration and irradiation typically are applied to eliminate undesired components and inactivate viruses. Thus, animal health and slaughter conditions must be highly controlled and meet strict sanitary specifications.
