3,3'-Diaminobenzidine (DAB) 97% (by HPLC), Sigma-Aldrich®
Supplier: SIGMA ALDRICH MICROSCOPY
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.

3,3'-Diaminobenzidine (DAB) membrane peroxidase substrate (50X)
Supplier: Rockland Immunochemicals
DAB membrane peroxidase substrate (50X) is a benzidine derivative oxidized by hydrogen peroxide in the presence of hemoglobin yielding a dark-brown colour of solution. This oxidation can be utilized for tissue samples by first preparing them with hydrogen peroxide.
