Reagent for Mapping Genome-Wide Enhancer-Promoter Interactions
This invention is a research reagent named the “bivalent Tn5 complex” used in transposition-mediated analysis of chromatin looping (TrAC-looping) to determine genome-wide enhancer-promoter interactions during studies of 4D nucleomes in normal development and disease conditions. Enhancer-promoter interactions are key in temporospatial control of gene expression during normal development and pathological conditions. Currently available methods of analyzing genome-wide enhancer-promoter interactions are insufficient in achieving necessary resolution, give rise to false positive artifacts due to in vitro ligation steps, or too expensive due to the necessity of sequencing over a billion reads. The instant reagent and associated TrAC-looping technique effectively reduce false positive detection and achieve a 10 to 100-times higher resolution at lower cost for mapping genome-wide interactions between enhancers and promotes essential for the control of gene expression in normal development and pathological conditions.
