Bovine Serum Albumin, also commonly referred to as BSA or Fraction V, is a high-purity protein isolated from bovine plasma. It is often utilized in enzyme-linked immunosorbent assay (ELISA) for its ability to block open binding sites. BSA has also been found to prompt the onset of insulin-dependent diabetes mellitus. Bovine serum albumin has many applications ranging from immunology, microbiology, tissue culture, and diagnostics.
