Figure 1From: Genomic mapping of RNA polymerase II reveals sites of co-transcriptional regulation in human cellsEnrichment of selected genomic regions in ChIP. (a) PolII ChIP; (b) PolIIa ChIP. Real-time PCR relative enrichment ratios for selected regions are found to be enriched more often with p-values below 10-4. These regions include both intra- and intergenic locations as listed in Additional data file 8.Back to article page
