title: GSM5550003: ATACseq D-iPSCs-2-1 Passage4; Mus musculus; ATAC-seq
library_construction_protocol: For ATAC-seq library, cells were lysed with a lysis buffer (10mM Tris-HCl pH7.4, 3mM MgCl2, 10mM NaCl and 0.1% IGEPAL CA-630). Yielded nuclei were suspended in the transposase reaction mix (25 µl of 2X TD Buffer (Illumina), 2.5 µl of TD Enzyme 1 (Illumina), and 22.5 µl of nuclease-free water), and incubated for 30 minutes at 37 ℃. Fragmented DNA was then purified using MinElute PCR purification kit (QIAGEN). After that, fragmented DNA was amplified by PCR to obtain ATAC-seq libraries. The libraries were paired-end sequenced with a length of 50 bp on Hiseq 1500 (Illumina).
