| Application: | Bovine Serum Albumin solution has been used as a standard for the quantification of protein in extracellular polymeric substances (EPSs) using the Lowry method. |
| Biochem/physiol Actions: | Bovine Serum Albumin (BSA) facilitates the transport of drugs, hormones, and fatty acids. It is used as a blocking agent in enzyme-linked immunosorbent assay (ELISA). BSA is an important constituent of the cell culture media and favors embryonic stem cells (hESC) differentiation. It plays a vital role in the cosmetic and pharmaceutical industry. |
| General description: | Bovine serum albumin (BSA) is a member of the serum albumin family. It is a globular, α-helical, and non-glycosylated protein. BSA is a single-chain protein and consists of three domains with two sub-domains under each. It has 17-disulfide bonds. |
