title: Coimmunoprecipitation assay for the detection of kinase-substrate interactions.
abstract: Coimmunoprecipitation is a powerful tool to study protein-protein interactions and can be used to test for the physical association between a known protein kinase and its substrate. In this chapter, the author describes a protocol for the preparation of a cell lysate, the immunoprecipitation of the antigen, and the analysis of the immune complex by gel electrophoresis and immunoblotting with antibodies that recognize the putative associated protein.
