Prepare a working concentration of TMB substrate solution within 15 minutes prior to use by mixing equal volumes of Substrate Reagent A and Substrate Reagent B (e.g. for one 96-well plate, a 12 mL TMB substrate working solution can be prepared by mixing 6 mL of Substrate A with 6 mL of Substrate Reagent B). When mixed together, TMB substrate solution should be colorless to a very faint blue. In the presence of peroxide-labeled conjugates, the solution should develop a definitive blue color. After the addition of sulfuric or phosphoric acid to stop the reaction, the color changes from blue to yellow.
