    摘要: 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.

    摘要: Methods and compositions are provided for improved kinetics of light production from luciferase activity in beetle luciferase-luciferin reactions. Thus, the invention provides methods, compositions and test kits for assaying samples for the presence of a beetle luciferase or, using a beetle luciferase-luciferin reaction, the presence of ATP. The invention also provides the complex of the coenzyme, Coenzyme A, a beetle luciferase and oxyluciferin in its exited state in the luciferase-luciferin reaction and luciferyl-CoA, the thioester of Coenzyme A and luciferin (D-(-)-2-(6'-hydroxy -2'-benzothiazolyl)-.DELTA..sup.2 -thiazoline-4-carboxylic acid).

    摘要: The present invention is directed to compositions and methods for single-step extraction and detection of ATP levels from microbial cells. The disclosed compositions are formulated to efficiently elicit bioluminescent detection of ATP among a broad variety of different microorganisms using a common single-step reagent composition. Additional luminescence-based methods are provided for identifying other useful extracting agents or for screening compounds for their pharmaceutical or biological effects on microbial cells.
