WebChIP, RIP, and Protein-Nucleic Acid Pull-Down Products. Chromatin 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. WebPull down assay using tagged proteins One of the major technical hurdles with immunoprecipitation is the great difficulty in generating an antibody that specifically targets a single known protein. To get around this obstacle, many groups will engineer tags onto either the C- or N- terminal end of the protein of interest. feldman used trucks
