General description

3,3′-Diaminobenzidine (DAB) is a chromogenic substrate for peroxidase enzyme. It is converted to an insoluble precipitate after oxidation by peroxidase.

Application

3,3′-Diaminobenzidine (DAB) Enhanced Liquid Substrate System tetrahydrochloride has been used:
  • in the detection of hydrogen peroxide in rice leaves
  • as a substrate for rabbit peroxidase in immunohistochemistry of mice brain sections
  • in immunocytochemistry of muscle-derived stem cells (MDSCs)

The DAB (3,3′-Diaminobenzidine tetrahydrochloride) Two-component Enhanced Liquid Substrate System is a precipitating substrate system for peroxidase. DAB Two-component Liquid Substrate System produces a brown precipitate for use in immunohistological and immunoblotting staining procedures.

Caution

Stable for up to 18 mo. when stored at 2-8 °C in the original container.

Quantity

Each DAB Two-component Liquid Substrate System will provide 100 mL of the 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.
