library_construction_protocol: ChIP-exo experiments were carried out essentially as described (Rhee and Pugh, 2012). Briefly, crosslinked cells were lysed, and chromatin pellets were isolated and then fragmented by sonication. Chromatin was then immunoprecipitated using antibody-conjugated magnetic beads, followed by DNA polishing, A-tailing, Illumina adaptor ligation (ExA2), and on beads digestion by lambda and recJ exonuclease. After elution of the single-stranded DNA, a primer was annealed to EXA2 and extended with phi29 DNA polymerase, then A-tailed. A second Illumina sequencing adaptor was ligated to exonuclease treated ends, and the products PCR-amplified and gel-purified. ChIP-exo libraries were prepared for sequencing using standard Illumina protocols; Reference paper: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3813302/ ChIP-exo-Seq
