Data used in this study are summarized in Supplementary Table 1 online. The NRSF ChIP-chip data (GEO accession #: GSE8489) were obtained by analyzing the bound DNA fragments in Jurkat cells with Affymetrix Human Tiling 2.0R arrays. Two independent ChIP samples and two mock IPs were profiled. The NRSF ChIP-seq data were collected from a previous study4 (link). In that study, DNA fragments bound by NRSF in Jurkat cells were sequenced with the next generation sequencer made by Illumina/Solexa. These experiments involved sequencing a ChIP'd sample as well as a negative control sample generated from reverse-crosslinked genomic DNA that had not undergone immunoprecipitation. The Oct4 and Nanog ChIP-seq data were collected from [10].
