Extraction protocol |
DNA was extracted using phenol/chloroform and sheared to approximately 400 bp using sonication. Non-methylated DNA was purified by single step CXXC Affinity Purification at 600mM NaCl as described in Illingworth et al., 2010. Libraries were prepared as follows using enzymes from New England Biolabs (NEB). End Repair was carried out by incubating immunoprecipitated DNA with T4 DNA polymerase, E. coli DNA Pol I large fragment (Klenow polymerase) and T4 polynucleotide kinase for 30 minutes at 20 C. The blunt, phosphorylated ends were treated with Klenow fragment (exo-) and dATP for 30 minutes at 37 C to yield a protruding 'A' base for ligation of Illumina's adapters which have a single 'T' base overhang at the 3’ end. Ligated DNA was extracted using MiniElute PCR clean up columns (Qiagen) and PCR amplified with Illumina primers for 10-12 cycles. Library fragments of ~250 bp (insert plus adaptor and PCR primer sequences) were isolated by gel extraction. The purified DNA was captured on an Illumina flow cell for cluster generation. Libraries were sequenced on the Genome Analyzer following the manufacturer's protocols. Sequencing was performed at the Wellcome Trust Sanger Institute; Hinxton, Cambridge, UK.

Description |
CXXC affinity chromatography

Data processing |
Alignment: Single-end sequence reads were mapped to the mouse genome (NCBIm37) using MAQ (http://maq.sourceforge.net/). Reads with a mapping score greater or equal to 30 where retained. Alignment was performed at the Wellcome Trust Sanger Institute; Hinxton, Cambridge, UK.
