title: GSM8836023: Phase1_aRUNX1_ChIP_rep2; Mus musculus; ChIP-Seq
library_construction_protocol: Ten million of Cas9-LPs with or without Notch stimulation were fixed with 1 mg/ml disuccinimidyl glutarate (Thermo Scientific) in PBS for 30 min at room temperature followed by an additional 10 min with addition of formaldehyde up to 1 %. The reaction was quenched by addition of 1/10 volume of 0.125 M glycine and the cells were washed with cold PBS. Pelleted nuclei were dissolved in lysis buffer (0.5 % SDS, 10 mM EDTA, 0.5 mM EGTA, 50 mM Tris-HCl [pH 8.0], and PIC) and sonicated on a Bioruptor (Diagenode) for 18 cycles of 30 sec sonication followed by 30 sec rest, with high power. ChIP-seq libraries were constructed using NEBNext Ultra Ⅱ DNA Library Prep with Sample Purification Beads (E7103S, NEB) and NEBNext Multiplex Oligos for Illumina (E7500S, NEB) and sequenced on Illumina NextSeq500 in single read mode with the read length of 75 nt.
