title: GSM6067799: MEFS-C1_BGI-7; Mus musculus; ATAC-seq
library_construction_protocol: OMNI-ATACseq libraries were generated from FACS purified cells (in case of MEFs: Thy1+ ; in case of mESCs: Thy1-/Ssea1+/Epcam+)  according to the standard protocol (see doi: 10.1038/nmeth.4396). Afterwards, libraries were purified using a QIAGEN MinElute PCR purification kit (QIAGEN, Cat#28004) followed by Agencourt AMPure XP beads (Beckman Coulter, Cat#A63880) according to the manufacturer's recommendations. Library fragments ranging from 150 to 700 bp were enriched and the final elution volume was 21 ul. The finalized libraries were provided to BGI for sequencing. HiSeqX10 sequencing was performed in 150bp PE mode followed by read trimming to 100bp PE for analysis. In case of sequencing on the DNBSEQ-G400 instrument libraries were converted to nanoballs and sequenced according to established workflows in 100bp PE mode (see doi: 10.1093/nargab/lqaa034).
