Foetal Bovine serum (FBS) is the liquid fraction of the clotted fetal blood. After separation by centrifugation, the raw FBS is then dispensed into containers and frozen. A batch of Sterile filtered FBS is obtained by thawing, pooling and filtration of raw FBS through a series of membrane filters culminating in a sterile 0.1 micron filter, before being aseptically dispensed.

Adult Bovine serum (ABS) is defined as the liquid fraction of clotted blood derived from healthy, slaughtered cattle 12 months of age or older, deemed to be fit for human consumption by ante- and/or post- mortem inspection.

Newborn Bovine Calf serum (NBCS) is defined as the liquid fraction of clotted blood derived from healthy, slaughtered bovine calves aged less than 20 days, deemed fit for human consumption through ante- and/or post-mortem inspection.

Using the heat shock method plus purification by extensive diafiltration at a low pH gives a more purified product (albumin fraction) than the Cohn process. This process is taking place in a closed system.
