Extraction protocol |
~ 1 x 106 cells, in a 10cm dish, were fixed by adding formaldehyde at a final concentration of 1% and incubating for 10 minutes at 37°C. The cells were washed twice with ice cold PBS containing protease inhibitors (1mM phenylmethylsulfonyl fluoride (PMSF), 1mg/ml aprotinin and 1mg/ml pepstatin A), harvested and treated with SDS lysis buffer for 10 min on ice. The resulting lysates were sonicated to shear the DNA to fragment lengths of 200 to 500 basepairs. The complexes were immunoprecipitated with antibody specific for histone 3 lysine 4 trimethylation (Abcam #ab8580). 10 ml of antibody was used. No antibody controls were also included, and no precipitation was observed by quantitative Real-Time PCR analysis. The antibody/protein complexes were collected by Protein A/G PLUS agarose beads (Santa Cruz sc-2003) and washed several times. The immune complexes were eluted with 1% SDS and 0.1 M NaHCO3 and samples were treated with proteinase K for 1 hour and DNA was purified by phenol/chloroform extraction, ethanol precipitation and resuspended in 30ml H2O. The ChIP DNA was quantitated using Qubit and 10ng was used for Illumina library preparation using Illumina ChIP-Seq DNA Sample Prep Kit #IP-102-1001.

Data processing |
Reads were mapped with bowtie 0.12.7 Only reads mapping uniquely to the genome were kept. Upto 3 mismatches to the reference sequence were allowed. When more than one read mapped to the same genomic position, only one read was kept at that position. Genome_build: hg18 Supplementary_files_format_and_content: BigWig. Counts across the whole genome in windows 20 bases wide, per 1 million mapped reads.
