Detection of Kinase Activity Using Versatile Fluorescence Quencher Probes

Abstract

(Figure Presented) Turn off the light! A kinase assay system employs fluorescent peptides and a phosphate-selective fluorescence quencher probe, and can be placed on a microfluidic chip (see picture). The system can be used for real-time kinase monitoring, kinase inhibitor screening, and cancer diagnosis based on abnormal kinase activity observed in patients' samples.
