Abstract
The present invention provides methods for screening for bioactive compounds, in particular those that bind to RNA sequences involved in the pathogenesis of disease or in regulation of a physiological function. The methods involve assessing the stability and/or the conformation of an RNA target in the presence and absence of test ligands, and identifying as a ligand any test ligand that causes a measurable change in target RNA stability and/or conformation. In a preferred embodiment, the effect of a ligand on target RNA stability and/or conformation is assessed by measuring the fluorescence polarization of a fluorescently labeled probe.
