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.

Other Notes

2024 CiteAb Award Winner for Supplier Succeeding in Parkinson′s Research

Preparation Note

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