Abstract:
A generic high-throughput screening assay based on the scintillation proximity assay technology has been developed for protein kinases. In this assay, the biotinylated (33)P-peptide product is captured onto polylysine Ysi bead via avidin. The scintillation signal measuring the product formation increases linearly with avidin concentration due to effective capture of the product on the bead surface via strong coulombic interactions. This novel assay has been optimized and validated in 384-well microplates. In a pilot screen, a signal-to-noise ratio of 5- to 9-fold and a Z' factor ranging from 0.6 to 0.8 were observed, demonstrating the suitability of this assay for high-throughput screening of random chemical libraries for kinase inhibitors.
