Description: This BK-1/39 monoclonal antibody reacts with biotin, a B-complex vitamin. As a coenzyme, biotin is involved in the metabolism of fatty acids, amino acids, and gluconeogenesis. In the laboratory, biotin is used to tag molecules of interest for biochemical or cell biological studies. This monoclonal antibody can be used to detect biotinylated proteins and antibodies, particularly if signal amplification is desired.
