Cells were crosslinked with 0.5 mg/mL disuccinimidyl glutarate (DSG; Thermo Fisher) in PBS for 45 min at room temperature. Cells were washed once with PBS followed by incubation with 1% PFA for 20 min at RT. Fixation was stopped by addition of glycine in PBS to a final concentration of 0.1 M for 3 min at RT. This was followed by washing with cold PBS and collection of the cells in 0.25% Triton X-100, 10 mM EDTA (pH 8.0), 0.5 mM EGTA (pH 8.0), and 20 mM Hepes (pH 7.6) in miliQ. Chromatin was pelleted by centrifugation for 5 min at 400 ×
