title: GSM2876096: K562_BG4-ChIP-rep_2_input; Homo sapiens; ChIP-Seq
library_construction_protocol: Chromatin was isolated from K562 cells that were cross-linked using 1% formaldehyde for 10 min at RT and prepared using a ChIP-qPCR Kit (Chromatrap, cat. no. 500117). Chromatin was sonicated using a Bioruptor Plus (Diagenode) to give a fragment distribution of 100-500 bp. G4 ChIPed DNA was subjected to Nextera library preparation (Illumina, cat. no. FC-121-1030).
