Monitoring of intracellular protein kinase activity is very important for fields involving diagnosis and drug screening. However, current methods, such as radiometry using 32P, or ELISA, are laborious and time-consuming. We have developed high-throughput assay system of protein kinase activity using mass-tagged substrate peptide probes and mass spectrometry. This assay system can easily evaluate target kinase activity and will potentially be able to simultaneously profile many protein kinase activities.
