Bovine serum albumin (BSA) is one of the most extensively utilized proteins across life sciences research. Derived through processing of bovine serum albumin fraction V, this highly purified BSA protein serves as a foundational reagent in biochemical and diagnostic workflows. With a well-characterized molecular weight of approximately 66.5 kDa and a defined sequence of amino acids, BSA offers exceptional stability and functional consistency.
At Equitech-Bio, Inc., our bovine albumin is manufactured under ISO 13485:2016-certified conditions, ensuring lot-to-lot reproducibility for demanding research applications. It functions as a reliable blocking agent in Western blotting and ELISA protocols, a stabilizer for primary antibodies, and an essential supplement in cell culture media.
Researchers also rely on BSA as a protein-concentrated standard in laboratory quantification assays.
Our BSA is tested for fatty acid content, endotoxin levels, and biochemical purity, making it suitable for sensitive assays. Each lot is traceable from source to final product, supporting compliance-driven research and diagnostic manufacturing environments.
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.
Equitech-Bio, Inc. supplies research-grade bovine serum albumin BSA directly to laboratories, diagnostic manufacturers, and academic institutions worldwide. Our bovine albumin products are manufactured under USDA oversight and ISO 13485:2016-certified processes, ensuring consistent purity and traceability.
