Diaminobenzidine - an overview | ScienceDirect Topics
Feb 7, 2012 · The reagent 3,3′-diaminobenzidine (DAB) is a sensitive alternative to protein stains for the enhancement of fingermarks in blood. Blood marks are first fixed with a solution of 5-sulfosalicylic acid. A buffered solution of DAB and hydrogen peroxide is then applied and the reaction allowed to proceed over ∼4 min.
DAB Immunohistochemistry
DAB (3,3'-diaminobenzidine) is oxidized in the presence of peroxidase and hydrogen peroxide resulting in the deposition of a brown, alcohol-insoluble precipitate at the site of enzymatic activity.DAB (3, 3’-diaminobenzidine) produces a dark brown reaction product and can be used for both immunohistochemical and blotting applications. ...

Detecting Horseradish Peroxidase-Labeled Cells - CSH Protocols
Diaminobenzidine (DAB) is the most commonly used substrate and one of the most sensitive. It yields an intense brown product that is insoluble in both water and alcohol. DAB staining is compatible with a wide range of common histological stains. DAB can be made more sensitive by adding metal salts such as cobalt or nickel to the substrate solution.
