library_construction_protocol: After the appropriate treatment, cells were collected by scraping and nuclei were isolated. Chromatin was digested with MNase. Sequentially, mononucleosomal fragments were immunoprecipitated, purified fragments were biotinylated, libraries were prepared, EdU-biotin fragments were pulled-down and sequenced. Libraries were costructed using the KAPA Hyperprep kit and Illumina-compatible indexed adapters (IDT, 10005903) following manufacturer's instruction. For the amplification step, 11 PCR cycles were used. Subsequently, the DNA underwent size selection using Agencourt AMPure XP beads (Beckman Coulter, A63881) to obtain fragments between 200-700 bp. Libraries were validated using Agilent Fragment Analyzer.
