The invention provides novel methods and compositions for detecting kinase activity in solution, without the use of radioactivity. The methods marry the kinetic advantages of solution-based reaction with the efficiency and high-throughput adaptability of solid-phase wash and detection steps, yet is conveniently practiced in a single tube. The methods may be used to assay for kinase activity per se or, by controlling for the kinase activity, for modulators of kinase activity. The method is exemplified with a preferred chemiluminescent protein kinase assay using biotinylated substrate peptides captured on a streptavidin coated microtiter plate and monoclonal antibodies to detect their phosphorylation. |
