Protocol for fractionation-assisted native ChIP (fanChIP) to capture protein-protein/DNA interactions on chromatin

Summary: Conventional chromatin immunoprecipitation (ChIP) includes many steps that need to be optimized. Here, we have described a protocol of fractionation-assisted native ChIP (fanChIP) which combines subfractionation and native ChIP to purify protein/chromatin complexes applicable for analyses of both protein-protein and protein-DNA interactions within a short period of time. fanChIP is advantageous as subcellular fractionation removes chromatin-unbound materials before immunoprecipitation, and the chromatin fragmentation by micrococcal nuclease (MNase) in a mild condition enables one-step purification of intact protein/chromatin complexes.For complete details on the use and execution of this protocol, please refer to Miyamoto et al. (2020).
