Immunoprecipitation (IP). Immunoprecipitation (IP) is the small-scale affinity purification of antigens using a specific antibody and is one of the most widely used methods for antigen purification and detection.This approach enables researchers to: 1  identify the activation status of proteins. 2  determine post-translational protein modifications.hromatin immunoprecipitation (ChIP) assays are performed to identify regions of the genome with which DNA-binding proteins, such as transcription factors and histones, associate. In ChIP assays, proteins bound to DNA are temporarily crosslinked and the DNA is sheared prior to cell lysis.
