library_construction_protocol: 50.000 cells were used for ATAC library preparation using Tn5 Transposase from Nextera DNA Sample Preparation Kit (Illumina). Cells were pelleted and resuspended in 50µl Lysis/Transposition reaction (12.5µl THS-TD-Buffer, 2.5µl Tn5, 5µl 0.1% Digitonin and 30µl water) and was incubated at 37°C for 30min with occasional snap mixing. Following purification of the DNA fragments was done by MinElute PCR Purification Kit (Qiagen). Amplification of Library together with Indexing was performed as described elsewhere (Transposition of native chromatin for fast and sensitive epigenomic profiling of open chromatin, DNA-binding proteins and nucleosome position. (2013) Jason D Buenrostro, Paul G Giresi, Lisa C Zaba, Howard Y Chang & William J Greenleaf. Nature Methods. doi:10.1038/nmeth.2688). Libraries were mixed in equimolar ratios and sequenced on NextSeq2000 platform (Illumina) using P2 flowcell with 2x 61bp paired-end setup.
