Fetal Bovine Serum (FBS) is a complex mixture with low and high molecular weight biomolecules exhibiting balanced growth-promoting and growth-inhibiting functions. FBS contains molecules, such as growth factors, proteins, vitamins, trace elements, hormones etc. These molecules are important for the growth and maintenance of cells. It is a common supplement for cell culture media.
Most Fetal Bovine Serum (FBS) batches do not support mouse ES cells. Sigma-Aldrich has pre-screened multiple FBS batches to increase your chances of selecting a batch that will perform within your laboratory, saving you time and money.
In addition to our extensive Fetal Bovine Serum performance and quality assays (mycoplasma, sterility, endotoxin, hemoglobin, etc.), we have developed low density, feeder-free assays to assess Fetal Bovine Serum′s support of mouse embryonic stem cells. Only those batches that performed well with mouse ES cells were selected for this product.

FBS derived from clotted blood is the most widely used undefined supplement in eucaryotic, especially mammalian, cell culture. It is typically used with the classical media that were developed in the 1950s and 1960s. These include many popular media such as Minimum Essential Medium (MEM); Dulbecco′s Modified Eagles Media (DME, DMEM); Iscove′s Modified Eagles Medium (IMDM); M199 and Roswell Park Memorial Institute medium, RPMI-1640.
