General description

Fetal Bovine Serum (FBS) remains a popular media supplement as it provides a wide array of functions in cell culture. FBS delivers nutrients, growth and attachment factors and aids in proliferation.[14] It also protects cells from oxidative damage and apoptosis.[51] FBS blocks reactive oxygen species generation, which otherwise is not eliminated in serum-free media (SFM) systems.[84]


FBS sourced in the United States is used in a broad range of cell culture applications. FBS provides many non-defined growth promoting and survival enhancing factor to cells in culture.
Fetal Bovine Serum has been used:
  • as a component of Dulbecco′s Modified Eagles Media (DME, DMEM),
[57] Eagle′s Minimum Essential Medium (EMEM),[89] Roswell Park Memorial Institute medium (RPMI-1640),[93] α-modified eagle medium (αMEM) (MEM)[25] and Leibovitz L-15 medium[92]
  • as a component of blocking medium for treating brainstem slices
  • [09]
  • to improve attachment of dermal explants
  • [39]

    Preparation Note

    Prepared by heating at 56°C for 30 minutes.
    This product is prepared by heating at 56°C for 30 minutes. Heating serum to 56°C for 30 minutes inactivates the complement system for immunoassays. Heat activation also inactivates other undetermined inhibitors of cell growth in culture.

    Analysis Note

    • Endotoxin and hemoglobin tested
    • Tested for the presence of bacteria, virus, and mycoplasma
    • Triple filtered with 0.1 micron membrane under aseptic conditions
