Abstract:
A method of monitoring the interaction between a substrate and a substance to which said substrate is exposed, which comprises:coupling a bioluminescent protein portion, capable of taking part in a bioluminescent reaction, to a first portion of said substrate, coupling an energy transfer protein portion to a second portion of the substrate, whereby said bioluminescent protein portion and said energy transfer protein portion are in an energy transfer relationship, exposing said substrate to said substance, initiating said bioluminescent reaction, and monitoring at least one of the amount of light emitted directly by said bioluminescent protein portion and the amount of light emitted by said energy transfer protein portion resulting from energy transfer between said bioluminescent protein portion and said energy transfer protein portion, wherein said substrate comprises a nucleic acid fragment containing one or more mutations or deletions and said substance comprises a nuclease responsive to said one or more mutations or deletions to cleave said nucleic acid fragment.
