Development of a novel fluorescent probe for fluorescence correlation spectroscopic detection of kinase inhibitors.
We have developed a fluorescently labeled probe for high-throughput screening of kinase inhibitors using fluorescence correlation spectroscopy. With this probe, we have successfully evaluated the inhibitory activities of known inhibitors of a model kinase, ASK1. Because the probe contains a general kinase inhibitor, staurosporine, we believe that this homogeneous, high-throughput, and simple method can be applied to the inhibitor screening of other kinases as well.
