title: GSM5968882: EdUHU, K562, RAD21-mAC-1, IAA, Repeat1; Homo sapiens; OTHER
library_construction_protocol: Genomic DNA was isolated, tagged with biotin by click-iT reaction, subjected to the sequential isolation of EdU. After on-beads ligation, purified DNA was tagged with Illumina sequencing primers and sequenced on Hi-seq, 2×150 bp. Nail-seq (Liu et al., 2021)
