Library construction for the Illumina platform was prepared using a custom procedure for paired-end sequencing (Illumina). Briefly, 2-10 ng of ChIP material was end-repaired and A-tailed before being ligated to TruSeq PE adaptors. The resulting material was then amplified using TruSeq PE PCR primer 1.0 and custom indexed multiplexing primers [5' AAGCAGAAGACGGCATACGAGATNNNNNNGTGACTGGAGTTCAGACGTGTGCTCTTCCGATC 3'], where "NNNNNN" corresponds to unique hexamer barcodes. PCR amplification was performed as follows: denaturation at 98°C for 60 seconds; 8 cycles of (98°C, 30 seconds; 65°C, 30 seconds; 72°C, 30 seconds), and a final extension at 72°C for 5 minutes. An aliquot of each library was run on an Agilent High Sensitivity chip (Agilent) to check the size distribution and molarity of the PCR products. Equimolar amounts of indexed, amplified libraries were pooled, and fragments in the 200-600 bp size range were selected on an 8% Novex TBE PAGE gel (Invitrogen). The pooled libraries were diluted to 15 nM. Libraries were sequenced on the Hiseq2000 (SBSxx) platform. The hexamer barcode was sequenced using the following primer [5' GTGACTGGAGTTCAGACGTGTGCTCTTCCGATCT 3']. Image analysis, base-calling and error calibration was performed using Illumina's Genome analysis pipeline.
