Abstract
Proximity ligation-assisted ChIP-Seq (PLAC-Seq), also known as HiChIP, is a method to detect and quantify chromatin contacts anchored at genomic regions bound by specific proteins or histone modifications. By combining in situ Hi-C and chromatin immunoprecipitation (ChIP) using antibodies against transcription factors (TFs) or histone marks of interest, the method achieves targeted interrogation of chromatin organization at a subset of genomic regions. PLAC-Seq is able to identify long-range chromatin interactions at kilobase-scale resolution with significantly reduced sequencing cost.
