3,3’ Diaminobenzidine (DAB) is a widely used chromogen for immunohistochemical staining and immunoblotting. When in the presence of peroxidase enzyme, DAB produces a brown precipitate that is insoluble in alcohol and xylene. Cardassian DAB comes in a 3-component system consisting of a liquid stable DAB Chromogen, DAB Substrate Buffer and DAB Enhancer. The enhancer adds contrast and a slight increase in staining intensity.
