Fetal Bovine Serum (FBS), Delipidated is used for applications, where a reduced lipid concentration in FBS is required, such as lipid metabolism studies or arteriosclerosis research. Fetal Bovine Serum (FBS), Delipidated is produced using the fumed silica precipitation method. When fumed silica is added to serum, non-polar substances, such as lipids and steroids, adsorb to the surface of the silica. The solution is then centrifuged and the pellet of fumed silica with adsorbed lipids is removed. The serum is then sterile-filtered. The acceptance criterion for the treatment is a level of cholesterol lower than 10 mg/100 ml. Lipids and other non-polar substances are reduced in comparison to non-treated serum. Fetal bovine serum (FBS) or fetal calf serum (FCS) is widely used in eukaryotic cell culture, typically as a supplement for growth media. Fetal bovine serum contains nutritional and embryonic growth promoting factors that are essential for a successful cell culture. Further, fetal bovine serum contains various small molecules, such as, e.g., amino acids, lipids, sugars, and hormones. Fetal bovine serum (FBS) is the blood component obtained after coagulation and removal of cellular components. Its unique and comprehensive mix makes FBS one of the most important supplements for supporting cell growth and proliferation for in vitro cell culture. Our fetal bovine serum for cell culture supports most cell lines and undergoes strict quality controls. This product is collected in South America.
