General description

3,3′-Diaminobenzidine (DAB) is a chromogenic substrate for peroxidase enzyme and is useful as a staining agent in immunohistological and immunoblotting techniques. The end product is resistant to alcohol therefore, a variety of counterstains and mounting media can be used with the DAB Liquid Substrate System. The DAB Liquid Substrate System provides all the chromogen and buffer/peroxide solutions needed to produce a fast and convenient DAB substrate solution..

Application

3,3′-Diaminobenzidine (DAB) Liquid Substrate System tetrahydrochloride has been used as a substrate:
  • in the immunoblot assay carried out to identify the changes in heat shock proteins (Hsps) expressed in the liver
  • for visualization of sections after immunostaining
  • in immunohistochemistry of mice knee joint sections
  • in the immunolabeling of kisspeptin neurons in the preoptic area of camel
It produces a brown precipitate with peroxidase for use in immunohistological and immunoblotting staining procedures. Not recommended for ELISA (microwell) procedures.

Caution

Stable at least one year at 2-8 °C.

Quantity

Each DAB Liquid Substrate System will provide 250 mL of DAB substrate solution.

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.
