title: GSM9684520: GBe11s17; Homo sapiens; ATAC-seq
library_construction_protocol: 1×10⁶ cells per replicate were washed in cold PBS and processed for ATAC-seq using the Active Motif ATAC-seq Kit (Cat. No. 53150) according to the manufacturer's protocol. Briefly, nuclei were isolated, and chromatin was tagmented with the kit-supplied Tn5 transposase. Tagmented DNA was purified and used directly for library amplification. ATAC-seq libraries were prepared and sequenced in-house using the Active Motif ATAC-seq Kit (Cat. No. 53150). Paired-end sequencing was performed on an Illumina instrument.
