3-[2-N-(Biotinyl)aminoethyldithio]propanoic Acid

3-[2-N-(Biotinyl)aminoethyldithio]propanoic acid features a biotin group and propanoic acid separated by a disulfide linkage. The carboxyl group of propanoic acid allows biotinylation of targets through either a chemical or enzymatic acylation reaction. The disulfide bond permits removal of the biotin group with reducing agents.Formal Name: 3-[[2-[[5-[(3aS,4S,6aR)-hexahydro-2-oxo-1H-thieno[3,4-d]imidazol-4-yl]-1-oxopentyl]amino]ethyl]dithio]-propanoic acid.
