Rabbit Anti-Bovine Albumin (BSA)-Agarose antibody has been used as a negative control in several immunoassays.

General description

Albumin, the major protein produced by liver cells, represents more than half of the total protein content of human serum. Many other body fluids also contain albumin. Three major functions for serum albumin have been proposed: maintenance of osmotic pressure, transportation of a variety of substances and an endogenous source of amino acids. The primary sites of albumin degradation are not known, but the protein can be metabolized by almost every organ in the body. Determination of serum albumin levels is a widely used screening test in clinical medicine. A decrease in serum albumin levels may indicate disease states such as malnutrition, cirrhosis, nephrotic syndrome, diabetes, gastrointestinal and hepatic diseases, thermal burns and pulmonary disease.

Rabbit polyclonal anti-Bovine Serum Albumin (BSA)–Agarose reacts with bovine albumin.
