Albumin fraction V

Description

• General description: Bovine serum albumin (BSA) belongs to the serum albumin family with three domains and two sub-domains each.[1][2] This globular, α-helical, non-glycosylated protein has 17-disulfide bonds.[1][2]
• Application: Albumin fraction V has been used: as a component of perfusion buffer for perfusion protocol for rodent organ perfusion [3]as a blocking agent in western blot analysis[4]as a nitrated protein standard to study the effects of antibodies against 3-nitrotyrosine and to characterize the binding and detection of nitrated proteins in one-sided and sandwich immunoassays[5]
• Biochem/physiol Actions: Bovine Serum Albumin (BSA) is the chief component of cell culture media[6] and also works as a blocking agent in enzyme-linked immunosorbent assay (ELISA).[7] It is beneficial for embryonic stem cells (hESC) differentiation and assists the transport of drugs, hormones, and fatty acids.[6][1]
