Methods and kits for discovery of rna-binding compounds

Abstract From the Canadian patent

A solution-based assay for identifying RNA binding compounds based on , competition. The assay comprises a reporter molecule carrying a fluorescent or chromogenic group that can form a one-to-one complex with an RNA target molecule carrying a second fluorescent or chromogenic group in such a way that the two groups are in sufficient proximity for fluorescence resonance energy transfer and/or quenching to take place. Addition of a compound-to-be-tested prevents formation of the complex and thereby increases the fluorescence of the RNA target and/or reporter molecules relative to the signal obtained in the absence of the test compound. Quantitative screening methods are also included.
