Sigma-Aldrich Fetal Bovine Serum

Sigma-Aldrich Fetal Bovine Serum (FBS) is a sterile-filtered, non-USA origin serum suitable for a wide range of mammalian cell culture applications. FBS remains the most widely used undefined supplement in cell culture due to its ability to provide essential nutrients, growth factors, and protective functions that are difficult to replicate in serum-free systems.

This formulation (Cat. No. F7524) is sourced from non-USA origin and undergoes rigorous quality testing. It is sterile-filtered three times through 0.1 μm membranes and tested for endotoxin (≤10 EU/mL), hemoglobin (≤25 mg/dL), and the absence of bacteria, viruses, and mycoplasma.

FBS is commonly used as a supplement in classical media such as Minimum Essential Medium (MEM), Dulbecco's Modified Eagle Medium (DMEM), Iscove's Modified Eagles Medium (IMDM), M199, and RPMI-1640. It supports the growth and maintenance of a variety of cell lines, including primary cells, immortalized lines, and hybridomas.
