Briefly, 5 x 106 cells were cross-linked with formaldehyde (1%, 10 min) then quenched with glycine (125mM). Fixed cells were lysed in SDS lysis buffer and chromatin-bound DNA sheared by sonication with a Misonix Sonicator S-4000. ChIP samples were incubated overnight at 4°C with Protein A Magnetic Beads (Millipore) and 5 μg of either H3K4me1 (ab8895; Abcam) or H3K27ac (ab4729; Abcam) antibodies. Protein-DNA cross-links were reversed by incubating overnight at 65°C and purified with the Zymo-SpinTM I kit (Zymo Research). Libraries were prepared from ChIP DNA (10ng) using the NEBNext® ChIP-Seq Library for Illumina (New England Biolabs) and Ampure XP Bead clean-up.
