Lysates were clarified from sonicated nuclei and histone-DNA complexes were isolated with antibody. We sheared chromatin using Bioruptor until reaching a fragment size of 200-500bp. 10-15μg of chromatin was then used for each replicate chromatin modification ChIP and 30μg for CTCF and RAD21 ChIP. ChIP for H3K4me1 (Abcam: 8898), H3K4me3 (Milipore: 07-473), H3K27Ac (Diagenode: C1540174), H3K27me3 (Milipore: 07-449), CTCF (Active motif: 613111) and RAD21 (Abcam: ab992) was then performed as in Lee et al., 2006. Libraries were prepared using the Nextera adaptors and sequenced.
