Extraction protocol |
Lysates were clarified from sonicated nuclei and CTCF-DNA complexes were isolated with antibody. Libraries were prepared according to Illumina's instructions accompanying TruSeq ChIP-seq Sample Preparation Kit. (Part# IP-202-1012). In brief, ChIP-enriched, fragmented DNA was subjected to end repair to generate blunt-end double stranded DNA, adenylation of 3’ ends, and adaptor ligation. Following ligation, SPRIselect (Beckman Coulter) beads were used at 0.9X and 0.6X for left and right side selection, respectively, to obtain an average library target size of ~300 bp. After size selection, fragments were amplified for 16 cycles, and PCR products were purified using Agencourt AMPureXP beads (Beckman Coulter).
