Chromatin was sheared to 200-400bp, incubated with H3K27ac antibody (abcam 4729) overnight at 4C on a rocker, antibody chromatin complex was captured by ProteinA agarose beads, washed with low salt, high salt, LiCl, and TE buffer, eluted and then de-crosslinked at 65C with 0.3M NaCl final for at least 6 hr. Final chormatin was purified using Qiagen PCR purification columns. Libraries were prepared using the Illumina Truseq ChIPseq Library preparation Kit following the manufacture's instructions (Illumina, CA).
