Time-resolved fluorescence resonance energy transfer (TR-FRET) protein-protein interaction assays, especially in the format of receptor-coregulator (coactivator and corepressor) recruitment/repression assays, have already been trusted in nuclear receptor research to characterize the settings of action, efficacies, and binding affinities of ligands (including their properties as agonists, antagonists, and inverse agonists). the binding affinities of PXR ligands… Continue reading Time-resolved fluorescence resonance energy transfer (TR-FRET) protein-protein interaction assays, especially in
