General description

3,3′-Diaminobenzidine tetrahydrochloride hydrate is a chromogen commonly used in immunohistochemistry and other staining techniques to visualize the presence of antigens or antibodies in biological samples. DAB HCl is designed as an immunohistology stain to visualize peroxidase activity in cells. DAB oxidation can be measured using a spectrophotometer.

Application

3,3′-Diaminobenzidine tetrahydrochloride hydrate is suitable for immunohistology staining procedures, western blotting, and FISH (fluorescence in situ hybridization). DAB is used in studying epithelial cell apoptosis in the event of early cataracts, and immunohistochemistry protocols of autosomal dominant polycystic kidney disease (PKD).

Biochem/physiol Actions

In the peroxidase reaction, DAB serves as a hydrogen donor in the presence of peroxide. The oxidized DAB forms an insoluble brown-colored complex.
