Application

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.
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

Reconstitution

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