Protein-mediated chromatin interactions can be revealed by coupling proximity-based ligation with chromatin ***,these techniques require complex experimental procedures and millions of cells per experiment,which limits their widespread application in life science ***,we develop a novel method,Hi-Tag,that identifies high-resolution,long-range chromatin interactions through transposase tagmentation and chromatin proximity ligation(with a phosphorothioate-modified linker).Hi-Tag can be implemented using as few as 100,000 cells,involving simple experimental procedures that can be completed within 1.5 ***,Hi-Tag is capable of using its own data to identify the binding sites of specific proteins,based on which,it can acquire accurate interaction *** results suggest that Hi-Tag has great potential for advancing chromatin interaction studies,particularly in the context of limited cell availability.
