From: Promoter capture Hi-C identifies promoter-related loops and fountain structures in Arabidopsis
Promoter capture Hi-C efficiently enriches promoter-related loops. A Schematic of the principles of promoter capture Hi-C. Ligated valid interactions prepared by the Hi-C library rarely include promoter-related loops (red). The library of core promoter baits with biotin marks is artificially synthesized and hybridizes with the Hi-C library. By pulling down the biotin-labeled fragments, the promoter capture Hi-C library with highly enriched promoter-related loops can be obtained. B Interaction decay exponent (IDE) curves of a published Hi-C library and the Hi-C library used in this study are indicated with green and blue, respectively. C Ratios of promoter-related interactions to all valid interactions for published Hi-C data and two replicates of PCHi-C are shown in a bar plot
