TMB Precipitating Reagent (For Membranes)
This liquid substrate for peroxidase consists of tetramethylbenzidine (TMB) plus dilute hydrogen peroxide in an aqueous single-reagent stabilized form. The reagent has been specifically formulated for measuring peroxidase on membranes and other surfaces. When reacted with peroxidase, the result is an insoluble blue reaction product. This reagent is not designed for use in microwell applications.
