Description

Thermo Scientific™ Pierce DAB and the DAB Substrate Kit enable chromogenic detection of horseradish peroxidase (HRP) activity based the action of 3,3'-diaminobenzidine (DAB) in blotting and tissue staining methods.

DAB (3,3'-diaminobenzidine tetrahydrochloride; MW = 214.1) reacts with HRP in the presence of peroxide to yield an insoluble brown-colored product at locations where peroxidase-conjugated antibodies are bound to samples. The brown precipitate is insoluble in alcohol and other organic solvents, making it an excellent substrate for immunohistochemical staining that requires the use of traditional counterstains and mounting media. The Pierce DAB Substrate Kit includes a 10X solution of DAB and Stable Peroxide Substrate Buffer. Crystalline DAB (powder) is also available.

Highlights:

  • HRP substrate – for detection of horseradish peroxidase activity on solid media, including nitrocellulose and PVDF membranes and fixed tissue samples

  • Chromogenic – no special equipment needed for visualization; the DAB reaction produces brown bands or spots at sites of reaction with HRP-conjugated antibodies or probes

  • Package options – choose powder for custom formulation with buffer and peroxide or a complete kit of preformulated solutions for immediate use
