Description générale

3,3′-Diaminobenzidine tetrahydrochloride hydrate is a chromogen commonly used in immunohistochemistry and other staining techniques to visualize the presence of antigens or antibodies in biological samples. DAB HCl is designed as an immunohistology stain to visualize peroxidase activity in cells. DAB oxidation can be measured using a spectrophotometer.

Application

3,3′-Diaminobenzidine tetrahydrochloride hydrate is suitable for immunohistology staining procedures, western blotting, and FISH (fluorescence in situ hybridization). DAB is used in studying epithelial cell apoptosis in the event of early cataracts, and immunohistochemistry protocols of autosomal dominant polycystic kidney disease (PKD).

Actions biochimiques/physiologiques

In the peroxidase reaction, DAB serves as a hydrogen donor in the presence of peroxide. The oxidized DAB forms an insoluble brown-colored complex.

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.
