Lysates were clarified from sonicated nuclei and histone-DNA complexes were isolated with antibody. ChIP-seq libraries were prepared from 10 ng of ChIP material per sample. NEBNext ChIP-Seq Library Prep Master Mix Set for Illumina (NEB #E6240L) and for the quantity measurement KAPA Library Quantification Kit (KapaBiosystems, #KK4824) was used according to the manufacturer’s instructions. 2 nM samples were multiplexed for sequencing.
