D7304 Sigma

3,3′-Diaminobenzidine (DAB) Liquid Substrate System tetrahydrochloride




Stable at least one year at 2-8 °C.


Each DAB Liquid Substrate System will provide 250 mL of DAB substrate solution.


DAB Liquid Substrate System is a precipitating substrate system for peroxidase. It produces a brown precipitate for use in immunohistological and immunoblotting staining procedures. Not recommended for ELISA (microwell) procedures. DAB has been used as a substrate in the immunoblot assay carried out to identify the changes in heat shock proteins (Hsps) expressed in the liver. It has been used as a substrate for visualization of sections after immunostaining.
