Chromatin immunoprecipitation (ChIP) with antibodies specific for Jmjd2a, H3K9me3, H3K36me3, H3K4me3 or H3. Adaptor-ligated libraries were generated from precipitated DNA using the NEBNext® Ultra DNA library kit for Illumina (New England Biolabs E7370L), subjected to gel-selection and PCR-amplified (15x PCR cycles) using indexed multiplex primers for Illumina sequencing (New England Biolabs E7335), and sequenced on a HiSeq 2000 using 50bp single-end sequencing.
