Application

Developed for use in immunohistology and immunoblotting as a precipitating substrate for the localization of peroxidase activity. DAB is the immunohistology substrate of choice as it produces an intense brown-black stain which is resistant to alcohol. Slides stained with DAB may be dehydrated, mounted in resinous media, and stored for future reference. SIGMAFAST™ DAB Tablets require no additional buffers or steps to prepare an active substrate solution. Tablets are individually packaged in foil packets
SIGMAFAST™ 3,3′-Diaminobenzidine tablets has been used as a chromogen for visualization in immunohistochemistry of gonad tissue, thymus, dental chronic periapical lesions and gall bladder sections.

Reconstitution

Each tablet set dissolved in 5 mL deionized water yields a ready-to-use buffered solution containing DAB and urea hydrogen peroxide.

Colorimetric Alkaline Phosphatase and Peroxidase Substrate Detection Systems

Nitroblue Tetrazolium (NBT) is used with the alkaline phosphatase substrate 5-Bromo- 4-Chloro-3-Indolyl Phosphate (BCIP) in western blotting and immunohistological staining procedures. These substrate systems produce an insoluble NBT diformazan end product that is blue to purple in color and can be observed visually.
