General description: | The metal enhanced DAB Substrate utilizes cobalt chloride and nickel chloride in a special formulation to produce a dark brown/black precipitate in the presence of horseradish peroxidase (HRP). 3, 3′ diaminobenzidine tetrahydrochloride (DAB) is a carcinogen that should be used safely. It is one of the major sensitive substrates for HRP (horseradish peroxidase). DAB is brown or amber in color and becomes insoluble and precipitates over the antigen-antibody site due to the presence of hydrogen peroxide and peroxidase. |
