Application

3,3′-Diaminobenzidine tetrahydrochloride hydrate has been used in immunohistological staining procedure and in situ hybridization.

Biochem/physiol Actions

DAB (3,3′-Diaminobenzidine) is utilized in many applications for the visualization of peroxidase activity. In the peroxidase reaction, DAB serves as a hydrogen donor in the presence of peroxide. The oxidized DAB forms an insoluble brown end-product for use in immunohistological and immunoblotting staining procedures.

Packaging

Weight approximate. Packaged in a 100 mL serum bottle with silicon/PTFE septum and aluminum tear seal.

Caution

Injecting a compatible solvent permits preparation of any desired strength solution without exposure.

Reconstitution

Dissolving the contents in 100 mL of solvent yields a 0.1% 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.
