Applicazioni

3,3?-diaminobenzidine-tetrahydrochloride-dihydrate (DAB) was used as a chromogen, for detecting the antigen-antibody complex. It is one of the most potent marker being used in immunochemistry, mostly at the electron and light microscope levels. It is used as a histological stain for peroxidase activity. Reaction between 3,3'-Diaminobenzidine and peroxidase forms a visible insoluble product. This approach has been used to assay activity of glutamate decarboxylase in rat cerebellar sections and to detect horseradish peroxidase presence on cultured cell surfaces.
