GSM3258918: Young_Daughter 4y5A; Mus musculus; ATAC-seq
cells were separated by pipetting and singularly subjected to fragmentation of open chromatin-regions using Tn5 transposase (Illumina), followed by a pre-amplification step, library preparation and subsequent paired-end sequencing. For the pre-amplification step, NEBNext Ultra II Q5 Master Mix was used with Primer 1: 5'GTCTCGTGGGCTCGGAGATGTGTATAAGAGACAG3' and Primer 2: 5'TCGTCGGCAGCGTCAGATGTGTATAAGAGACAG3'. For dual-indexing, 10 μL of the pre-amplified ATAC reaction was used as input for Nextera index kit (Illumina). The generated libraries were quantified using agilent bio-analyzer and qPCR kit (New England Biolabs).
