Extraction protocol |
ChIP protocol is modified from Rayman et al, 2002. The purification and extraction of ChIP DNA from the IPs is described in the protocol (pdf file) attached to the Series record. Briefly, it involves purification using the Qiagen QiaQuick PCR purification columns (Cat. No. 28104). The LIN9 antibody used in ChIP was manufactured in-house in collaboration with Bethyl labs. The B-Myb antibody used in ChIP was from Bethyl labs, Cat. No. A301-656A. The average insert size of the ChIP-Seq libraries was 150-300 bp including adapters, 50-150 without adapters, as determined by running 1 ul of the library on the Agilent BioAnalyzer. Chromatin from HeLa cells was used to immunoprecipitate B-Myb or LIN9 using specific antibodies. From ~30 ng of chromatin IPed DNA or input DNA, libraries were prepared using Illumina's ChIP-Seq sample prep kit. ChIP-Seq DNA libraries were quantified using Nanodrop (Thermo-Scientific) and a sharp peak at 200-400 nt was confirmed on the BioAnalyzer (Agilent) before sequencing. Diluted libraries were used for cluster generation and single-end sequencing using the Genome Analyzer II (Illumina).

Data processing |
Base calling and mapping of the 36-bp reads to the human genome (Build 37, hg19) was done using Bowtie using very strict alignment criteria: only perfect matches (-n 0) and only unique alignments (-m 1). Enriched genomic regions from ChIP-Seq experiments were determined using CisGenome version 1.2 by two-sample analysis using the Input signal as negative control. The ChIP-Seq libraries were used for cluster generation and single-end sequencing (36-bp reads) using the Genome Analyzer II (Illumina) following the manufacturer's protocol.
