30014.K 3,3'- Diaminobenzidine DAB Chromogen 1 ml
H2O2 DAB Substrate 20 ml
DAB (3,3'-Diaminobenzidine) leads to the formation of a dark-brown precipitate at the location of the target antigen. The precipitate is insoluble in aqueous and organic solvents allowing the use of commonly known mounting media. This chromogen/substrate system is especially useful when a high contrast between the chromogen and counter stain is desired. Compared to standard DAB staining kits the HISTOLS®-DAB Chromogen/Substrate System gives a darker brown color and a higher sensitivity.
