library_construction_protocol: ChIP-seq for histone marks in MEFs: Cells were crosslinked by 1 % Formaldehyde for 10 min at room temperature and stopped with 125 mM Glycine for 5 min. Samples of around 40 million cells were treated with 40 U of MNase for 15 min at 37 °C. The samples were shared for 15 min (Burst 200; Cycle 20%; Intensity 8). Replicate 1 was shared for 30 min and no MNase treatment was performed. 4µg of antibody was used per sample and incubated for 2 hours at 4 °C. Protein G-beads were added over night. Multiple low and high salt washes were performed and the samples were eluted. Samples were reverse crosslinked and stored at -20°C. ChIP-seq for histone marks in MEFs: Libraries were made using NEBNext Ultra™ II DNA Library Prep Kit for Illumina (New England Biolabs, E7645)
