IHC chromogen substrate (DAB), tablets can be used in conjunction with peroxidase-based immunostaining systems. Peroxidase reacts with substrate 3% hydrogen peroxide to degrade it, which in turn reacts with DAB to precipitate it at the positive sites giving a dark brown color.

Scientific Background:DAB is a chromogen of choice when performing immunoperoxidase staining. It has been well accepted by the pathologist because of its superior performance as compared to amino ethyl carbazol (AEC). DAB is much more sensitive and gives cleaner background as opposed to AEC. Specimens stained in DAB can be dehydrated in ethanol, cleared in xylene, and mounted for permanent record keeping. However, because of its carcinogenic nature, some labs avoid handling DAB powder. To resolve this problem, we have designed DAB in tablet form to minimize the exposure of DAB particles to the lab personnel.
Technical Info/Product Notes:Interpretation of the results will be the sole responsibility of the user.
