Leírás

Általános leírás

Bovine serum albumin (BSA) belongs to the serum albumin family with three domains and two sub-domains each. This globular, α-helical, non-glycosylated protein has 17-disulfide bonds.

Alkalmazás

Albumin fraction V has been used:

• as a component of perfusion buffer for perfusion protocol for rodent organ perfusion
• as a blocking agent in western blot analysis
• 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

Biokémiai/fiziológiai hatások

Bovine Serum Albumin (BSA) is the chief component of cell culture media and also works as a blocking agent in enzyme-linked immunosorbent assay (ELISA). It is beneficial for embryonic stem cells (hESC) differentiation and assists the transport of drugs, hormones, and fatty acids.
