Cellular lysates were treated with micrococcal nuclease in order to digest genomic DNA. HIF-1α-DNA complexes were isolated with antibody. Library preparation and Illumina sequencing were performed by the IPBLN Genomics Core Facility (CSIC, Granada, Spain). ChIP-seq libraries were generated from 30 ng of DNA using the NEBNext Ultra II DNA library preparation kit for Illumina (NEB), and following manufacturer´s instructions with some modifications. A 10-fold dilution of adaptor was used in ligation reaction and no size selection was applied to the adaptor-ligated DNA clean up step, as recommended for Micrococcal Nuclease digested chromatin ChIP assays. A total of 5 cycles of amplification were used to complete adaptor sequences and introduce unique indices for sample multiplexing. Final libraries were quantified on the Qubit® fluorometer (Thermo) and run on a Bioanalyzer HS DNA chip to verify quality and size distribution. Equimolecular library pool was prepared, then diluted and denatured as recommended by Illumina NextSeq 500 library preparation guide. The 75 nt single-end sequencing was conducted on a NextSeq 500 sequencer (Illumina). An average of 24 million reads per sample was obtained.
