Descrição

3,3'-Diaminobenzidine (DAB) is an organic compound derived from benzidine. It is the precursor to the synthetic fibre polybenzimidazole (PBI), which have high thermal and oxidative stability properties. DAB is water-soluble as the tetrahydrochloride salt and is used in immunohistochemical staining of nucleic acids and proteins. Research in Alzheimer's disease, Aβ protein amyloid plaques are targeted by a primary antibody, and subsequently by a secondary antibody, which is conjugated with a peroxidase enzyme. This will bind DAB as a substrate and oxidize it, producing an easily observable brown colour. 3,3’-Diaminobenzidine is also available as the tetrahydrochloride salt and the tetrahydrochloride hydrate.
