A novel protein kinase assay was developed, based on FRET between QDs and fluorescently-labeled substrate peptides. The negatively charged QDs recognize the change in net charge of the peptide upon phosphorylation. Despite its simple mechanism, this assay is sensitive and robust enough to be applied to the evaluation of protein kinase inhibitors.
