Protein complexes are responsible for major biological processes in cells. Identifying a protein’s interaction partners reveals many different aspects related to the target such as its function, regulation, and mechanisms of action. Co-immunoprecipitation (co-IP) followed by shotgun proteomics is a powerful technique for capturing and identifying endogenous protein complexes. Although it is a simple concept, performing the experiment can be challenging due to the number of steps and the diversity of available protocols. Here we present a certified and detailed protocol to perform co-IP experiments in cultured human oligodendrocytes cells.
