DAB Membrane Substrate



Add to Cart


DAB Membrane Substrate is supplied as a two component liquid substrate system designed for the rapid and simple detection of peroxidase in membrane applications. The two components consist of DAB Membrane Concentrate (Reagent A) and DAB Membrane Reaction Buffer (Reagent B) which is a ready to use buffer containing hydrogen peroxide. DAB (3,3’-diaminobenzidine) is oxidized in the presence of peroxidase and hydrogen peroxide resulting in the deposition of a brown alcohol-insoluble precipitate at the site of enzymatic activity. The precipitate may range in color from a light golden brown to dark brown depending upon the amount of enzyme present.
