WebChromatin immunoprecipitation (ChIP) tips and tricks, containing cross-linking, fragmentation, antibodies, and detection away Dr Guardrail, Gurdon Institute. WebN-ChIP is suitable for targets such as histones and histone modifications. However, it is important to note that, without additional cross-linking, in vivo modifications in nucleosomes may still occur during your analysis. When targeting proteins that bind weakly to DNA, we highly recommend a crosslinking ChIP (X-ChIP) protocol.
WebMay 30, 2024 · A ChIP assay was performed by sequential protein-DNA cross-linking by various NHS-ester-containing cross-linking reagents (see Table 1) and compared with the immunoprecipitation efficiency of fixation by FA alone. Immunoprecipitations were performed on control (-) or TNF-stimulated (+) cells using anti-NF-κB/Rel A antibody. http://www.proteinguru.com/protocols/IP%20guide2.pdf
