Data visualized in the Integrative Genomics Viewer [47]. a H3K4me3 distribution in an 80 kb genomic region. A single example PCR-free library is shown in black at the top, and libraries derived from 1 ng and 0.1 ng are shown in grey and light grey respectively.b Data for all libraries shown as heat maps of the same genomic region. Y-axis scale in all cases is read depth 0–28
