摘要:
A method and kit is provided for enhancing the tolerance of an assay reagent to compounds in an assay sample, the assay reagent including a luciferase enzyme. The method includes contacting the luciferase with a tolerance enhancement agent in an amount sufficient to substantially protect luciferase enzyme activity from interference of the compound and minize interference by at least about 10% relative to an assay not having tolerance enhancement agent.
摘要:
The present invention provides compounds and methods for assaying redox state of metabolically active cells and methods for assaying enzyme activity and/or metabolite level by coupling to redox defining co-factor NAD(P)/NAD(P)H measurement.
摘要:
The invention provides methods that employ derivatives of 2-cyano-6-hydoxy- or 2-cyano-6-amino-benzothiazole, for example, in a bioluminogenic reaction. The invention further provides methods for detecting or determining the presence of molecules and/or enzymes, the modulator activity of such molecules, and/or the activity of such enzymes. The methods are adaptable to high-throughput format.

摘要:
Methods, kits and compositions containing a mixture of D-luciferin and L-luciferin for light generation with luciferase are disclosed that have improved stability when stored over time. The mixture of D-luciferin and L-luciferin can be used to detect the presence or amount of ATP or of luciferase in a sample.
摘要:
Provided herein are methods for the real-time monitoring of an intracellular event or response. In particular, the methods provided herein monitor the conversion of a pro-substrate to a substrate for a protein sensor as a result of an intracellular event or response.
