Co-Immunoprecipitation (Co-IP)

  Co-IP studys protein interactions, validating two known protein interactions and studying unknown proteins in total proteins that interact with target proteins. The method is: forming "target protein A-target protein B" complex and incubating with the complex with specific antibody of the target protein to promote the formation of the immune complex. The antibody/antigen complex is then raised using protein A/G coupled agarose gel. Qualitative analysis of the interaction between two proteins by Western blot or mass spectrometry
