Abstract

Abstract The present invention relates to single and dual-reporter luminescence assays utilizing general and specific reagents to quench enzyme-mediated reactions. In one embodiment of the invention, a reagent is added to the assay which non-specifically quenches enzyme-mediated luminescent reactions. In another embodiment of the invention, a reagent is added to the assay which simultaneously quenches one enzyme-mediated luminescent reaction while activating another distinct enzyme-mediated luminescent reaction. An assay kit containing specific quench reagents, and the reagents themselves are also disclosed.
