After fixation, the cells were permeabilized with 0.2% Triton-X in PBS and EdU was coupled to a cleavable biotin-azide linker (Azide-PEG(3+3)-S-S-biotin) using the Click-it Kit. Purification of genomic DNA was then performed by phenol-chloroform extraction and ethanol precipitation and subjected to EdU-labelled DNA isolation. Purified EdU-labeled DNA was used for library preparation with TrueSeq ChIP Library Preparation Kit (Illumina) and high-throughput 100-bp single-end sequencing was performed on Illumina Hi-Seq 4000 sequencer.
