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

Reconstitution

Each tablet set dissolved in 1 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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
