Thermo Fisher, 10082147, Fetal Bovine Serum, certified, heat inactivated, United States

Gibco™ Fetal Bovine Serum, certified, heat inactivated, United States is used as a nutrient-rich supplement for mammalian cell culture. This 500 mL bottle contains fetal bovine serum sourced from the United States and processed with a heat-inactivation treatment. The certified grade has an endotoxin specification of ≤5 EU/mL and a hemoglobin specification of ≤15 mg/dL, supporting applications that require controlled serum quality. FBS supplies proteins, attachment factors, hormones and other components that support growth and maintenance of many established and primary cell types. The product is shipped frozen and should be stored at or below -10°C. This formulation is useful when an established protocol specifically calls for heat-inactivated, U.S.-origin serum rather than untreated FBS, helping laboratories maintain consistency when reproducing validated culture conditions.
