title: GSM5582386: N-23.28_ATAC; Homo sapiens; ATAC-seq
library_construction_protocol: 50,000 MACS-sorted CD34+/CD45+ cells from each individual iPSC line were processed as follows: nuclei were isolated by lysis with 50 ul of ATAC lysis buffer (10 mM Tris pH 7.4, 10 mM NaCl, 3 mM MgCl2, 0.1% NP40, 0.1% Tween-20, and 0.01% Digitonin) and washed with 1 mL of ATAC wash buffer (10 mM Tris pH 7.4, 10 mM NaCl, 3 mM MgCl2, 0.1% Tween-20). Cell lysates were spun to obtain nuclear pellets, which were subjected to transposase reaction using the Illumina Nextera DNA Sample Preparation Kit according to the manufacturer's instructions. The libraries were quantified using the Agilent BioAnalyzer. Sequencing of 75 nucleotide-long paired-end reads was performed in a NextSeq-500 (Illumina).
