|
| Treatment protocol |
For Pol II ChIP-Seq, cells were not treated prior to cross-linking.
|
| Growth protocol |
Lymphoblastoid cell lines were grown in RPMI-1640 Medium, supplemented with glutamine, 15% FBS, and antibiotics (penicillin-streptomycin) at 37C in 5% CO2, to a density of 6-8 x10^5 cells/ml.

| Extracted molecule |
genomic DNA |
| Extraction protocol |
Chomatin immunoprecipitation was performed as previously described (Euskirchen et al. 2007; Rozowsky et al. 2009). 2 x 10^8 cells were cross-linked in 1% formaldehyde for 10 minutes at room temperature. The cross-linking reaction was quenched by adding glycine to a final concentration of 125 mM. Nuclear lysates were sonicated using a Branson 250 Sonifier (power setting 2, 100% duty cycle for 7 × 30-s intervals), such that the chromatin fragments ranged from 50-2000kb. Clarified lysates were divided in half and treated overnight at four degrees Celsius with 24μg of either mouse monoclonal 8WG16 antibody (Covance MMS-126R) or normal mouse IgG (Millipore #12-371). Protein-DNA complexes were captured on Protein A agarose beads (Upstate #16-156) and eluted in 1% SDS TE buffer at 65°C. Following cross-link reversal and purification, the ChIP DNA sequencing libraries were generated according to Illumina DNA Sample Kit Instructions (Illumina Part # 0801– 0303). The protocol was modified such that enzymes were obtained from other suppliers, as described in Auerbach et al. 2009.

| Data processing |
FASTQ files are either the sequence.txt files from the Illumnia pipeline (which exclude low quality reads) or, when available, are generated from the Illumina export.txt files which include all reads. Both types of alignment files, eland_result.txt and eland_multi.txt, are directly out of the Illumnia pipeline and unmodified. The narrowPeak files are the scored results generated from the PeakSeq pipeline (http://www.ncbi.nlm.nih.gov/pubmed/19122651?dopt=Abstract) and formatted in the UCSC narrowPeak format.
