Bovine serum albumin BSA is a globular plasma protein derived from cattle blood, widely used in laboratory research. With a defined molecular weight and a specific amino acid sequence, it provides exceptional stability in aqueous environments. It is structurally analogous to human serum albumin and is a standard reference protein in many biochemical applications across diagnostics and life sciences.

BSA protein in powder form is used as a blocking agent in Western blotting and ELISA, a stabilizer for primary antibodies, and a supplement in cell culture media. It also serves as a reliable protein concentration standard in quantification assays. Its low-fatty-acid variant is preferred in applications requiring minimal lipid interference. Reaction tubes containing BSA-stabilized solutions are common in molecular biology workflows.

Yes, 'bovine serum albumin', 'albumin bovine serum, and 'bovine albumin' all refer to the same protein. The terminology varies by manufacturer or application context. The BSA protein is isolated from bovine serum albumin fractions and shares structural similarity with human serum albumin. Regardless of the terminology used, the protein's molecular weight, amino acid composition, and functional characteristics remain consistent across preparations.
