Span distribution of intra-chromosomal PETs and the cutoff between self-ligation PETs and inter-ligation PETs. (a) The distribution of the intra-chromosomal PET genomic spans. (b) The log-log plot of interaction frequencies against PET span, and the cutoff between self-ligation PETs and inter-ligation PETs. (c) Agarose gel of chromatin DNA fragments prepared for ChIA-PET analysis. Selected DNA sizes are marked.
