PROPERTIES Enzyme Immunoassay for the quantitative determination of Biotin (Vitamin H) in food PRODUCT DESCRIPTION Biotin serves as the prosthetic group of enzymes, which catalyze carboxylations in the organism. For this purpose, biotin is bound via its carboxy group to lysin residues of carboxylases, and the transfer of carbon dioxide takes place after its attachment…
