Everything you should know about Bovine Serum Albumin

Bovine serum albumin is a serum albumin protein isolated from cows. Bio Pherotics generates BSA in diverse formats for use in immunology, biochemistry, as well as biotechnology. BSA immunoassay applications comprise ELISA (Enzyme-Linked Immunosorbent Assay), immunoblots (Western blot and dot blot), as well as immunocytochemistry (immunohistochemistry and immunofluorescence microscopy). BSA (often from a fetal bovine source) is also utilized as a nutrient in cell and microbial civilization.

In molecular biology, BSA is utilized to steady some constraint enzymes during digestion of DNA as well as to prevent adhesion of the enzyme to reaction tubes, pipet tips, along with other vessels. BSA is considered to be a worldwide blocking reagent in numerous applications—this is because BSA does not influence the functions of other proteins (enzymes) that do not need it for stabilization. BSA is also frequently utilized to determine the quantity of other proteins, by comparing an unidentified quantity of protein to known amounts of BSA in, for instance, the Bradford Protein Assay. BSA is used because of its constancy to increase signal in assays, its lack of effect in many biochemical reactions, as well as its low cost, since large quantities of it can be voluntarily purified from bovine blood, a byproduct of the cattle industry.

All products of animal origin, including products derived from bovine sources, are manufactured by Bio Pherotics and derived from starting materials of North American origin. Collection is executed in United States Department of Agriculture (USDA) inspected facilities and all materials have been inspected as well as specialized to be free of disease. Diseases linked with bovine products, particularly BSE (Bovine Spongiform Encephalopathy) or Mad Cow Disease, have been linked with bovine products originating in Europe.
