Immunoprecipitation (IP)-based techniques are one of the key techniques to study the interaction between proteins and other macromolecules, such as Co-IP (Co-immunoprecipitation) to study protein-protein interactions, RIP (RNA binding protein immunoprecipitation assay) to study protein-RNA interactions, and ChIP (chromatin immunoprecipitation assay) to study protein-DNA interactions.Learn more: rip seq
