Defining protein-protein interaction networks is a major goal of proteomics. Here, we present a protocol for coimmunoprecipitation, a technique suitable for the isolation of whole protein complexes in vivo and their subsequent identification by either immunoblotting or mass spectrometric sequencing combined to database search.
