title: GSM7256894: CD28 CAR, day 17, biol rep 2, ATACseq; Homo sapiens; ATAC-seq
library_construction_protocol: Omni-ATAC protocol: Nuclei were isolated from 50,000 sorted CART19 cells, followed by the transposition reaction using Tn5 transposase (Illumina) for 30 minutes at 37°C with 1000rp mixing.Purification of transposed DNA was completed with DNA Clean and Concentrator (Zymo) Omni-ATAC protocol: DNA fragments were barcoded with ATAC-seq indices.Final libraries were double size selected using AMPure beads prior to sequencing.
