Genomic DNA was extracted from microdissected FFPE sections using the QIAamp DNA FFPE Tissue Kit. 500ng gDNA was used for library preparation. The quantity and size distribution of libraries were determined using the Pico Green fluorescence assay and the Agilent 2100 Bioanalyzer, respectively. Libraries were sequenced as 150bp paired-end reads with planned 30x coverage per sample.
