Descripción

General description

3,3′,5,5′-Tetramethylbenzidine dihydrochloride hydrate (TMB-d) is a sensitive chromogen substrate for peroxidase. It is non- carcinogenic, hence, it can be used as a safe substitute for benzidine. TMB-d is useful in quantifying hemoglobin and in staining myeloperoxidase-containing granules in granulocytes.

Application

3,3′,5,5′-Tetramethylbenzidine dihydrochloride hydrate has also been used as a horseradish peroxidase substrate in enzyme linked immunosorbent assay and reverse dot blot (RDB).

Noncarcinogenic substitute for benzidine.
