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.

Application of 3,3'-Diaminobenzidine DAB£ü91-95-2
1.3,3'-diaminobenzidine ( CAS NO: 91-95-2/ DAB) Monomer used as a high temperature resistant polymer.
2.Anion-exchange Properties
DAB has unique anion-exchange properties that result in high selectivity for Rhodium (III) over Palladium (II) and Platinum (IV) in a concentrated Hydrochloric Acid Solution .
Future Directions
DAB has a wide range of applications in both academic and industrial settings. One of its most common uses is in immunohistochemistry, where it is used as a coupling reagent to detect the presence of certain proteins . It is also employed in the synthesis of certain dyes and serves as a precursor in the production of various azo dyes, which are commonly used in textile manufacturing and other industries
