"WebCross-linking ChIP or X-ChIP uses formaldehyde fixation of chromatin complexes bound to DNA. Nuclei are then lysed and the DNA is sheared and co-immunoprecipitated with antibodies to histones or histone modifications. Next, the crosslinking is reversed and DNA is purified for downstream analysis. Native ChIP (NChIP) is an otherwise similar ... " - Chip formaldehyde
