library_construction_protocol: Chemical labeling-based 5hmC enrichment was performed according to Hydroxymethyl Collector™ kit from Active Motif (cat#55013, Active Motif-Carlsbad, CA) to selectively label 5hmC bases with glucose and biotin moieties to form biotin-N3-5-gmC as previously described by Song et al (Song CX, et al. (2011) Selective chemical labeling reveals the genome-wide distribution of 5-hydroxymethylcytosine. Nature biotechnology 29(1):68-72). Briefly 4 ug of genomic DNA was sonicated with COVARIS S2 to target size 200-400 bp (250 bp protocol for 150 seconds), purified with 1X AMPure XP beads (Agencourt A63880) and then subjected to biotin-based enrichment of 5-hydroxymethylcytosine following the recommended procedure. Captured 5hmc DNA enriched fragments were then processed for Illumina sequencing as previously described (Garber et al. 2012) with slight modifications (Ostuni et al. 2013).
