title: GSM7785000: MSL1_m1GS, rep1; Drosophila melanogaster; ChIP-Seq
library_construction_protocol: Chromatin samples containing 10–20 µg of DNA equivalent in 200 µL of nuclear lysis buffer (2 µL aliquots of such pre-cleared chromatin being stored as input material) were incubated overnight, at 4°C, with antibodies-Dynabeads complexes. After 3 rounds of washing with lysis buffer supplemented with 500 mM NaCl, and TE buffer (10 mM Tris-HCl, pH 8; 1 mM EDTA), the DNA was eluted with elution buffer (50 mM Tris-HCl, pH 8.0; 1 mM EDTA, 1% SDS), the cross-links were reversed, and the precipitated DNA was extracted by the ChIP DNA Clean &Concentrator kit (Zymoresearch). The ChIP-seq libraries were prepared with NEBNext®_Ultra™_II DNA Library Prep kit, as described in the manufacturer's instructions. Amplified libraries were quantified using fluorometry with DS-11 (DeNovix, United States) and Bioanalyzer 2100 (Agilent, United States). Diluted libraries were clustered on a pair-read flowcell and sequenced using a NovaSeq 6000 system (Illumina, United States).
