3,3′-Diaminobenzidine has been used as a chromogen for the visualisation in immunohistochemistry of chondrosarcoma sections, mammary carcinomas and brain tissue sections. Peroxidase substrate; reagent for spectrophotometric determination of selenium. DAB (3,3′-Diaminobenzidine) is utilized 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 the immunohistological and immunoblotting staining procedures.
