3,3'-Diaminobenzidine tetrahydrochloride hydrate, ISOPAC®, Sigma-Aldrich®
Supplier: SIGMA ALDRICH MICROSCOPY
3,3′-Diaminobenzidine tetrahydrochloride hydrate has been used in immunohistological staining procedure and in situ hybridisation. DAB (3,3′-Diaminobenzidine) is utilised in many applications for the visualisation of peroxidase activity. In the peroxidase reaction, DAB serves as a hydrogen donor in the presence of peroxide. The oxidised DAB forms an insoluble brown end-product for use in immunohistological and immunoblotting staining procedures.

3,3'-Diaminobenzidine tetrahydrochloride (DAB HCl) kit peroxidase substrate
Supplier: Biotium
DAB (3,3′-diaminobenzidine) reacts with HRP in the presence of peroxide to yield an insoluble brown-colored product at locations where peroxidase-conjugated antibodies are bound to samples. The brown precipitate is insoluble in alcohol and other organic solvents, making it an excellent substrate for immunohistochemical staining that requires the use of traditional counterstains and mounting media.

3,3'-Diaminobenzidine tetrahydrochloride hydrate ≥96%, Sigma-Aldrich®
Supplier: SIGMA ALDRICH MICROSCOPY
3,3'-Diaminobenzidine tetrahydrochloride hydrate is a chromogen commonly used in immunohistochemistry and other staining techniques to visualise the presence of antigens or antibodies in biological samples. DAB HCl is designed as an immunohistology stain to visualise peroxidase activity in cells. DAB oxidation can be measured using a spectrophotometer.
