title: GSM6051711: Sm2-Ctrl2; Homo sapiens; ATAC-seq
library_construction_protocol: Cells were washed twice with 1X PBS and collected by scraping or pelleting prior to counting. Approximately 50K cells were pelleted and processed in duplicate as described in the Omni-ATAC-seq protocol published by Corces et al (Nature Methods, 2017). Uniquely indexed sequencing adapters from the Nextera DNA CD Indexes Kit were added to both ends of transposed fragment libraries by PCR. Following final purification and size selection for 100-1000 bp fragments, libraries were pooled and sequenced on an Illumina NextSeq instrument using 37 bp paired-end reads.
