library_construction_protocol
Dead cells were removed, cells formaldehyde treated and pellets snap frozen. Pellets were resuspended in sonication buffer, sonicated and lysed in RIPA buffer before performing ChIP with the appropriate antibody. ChIP-seq libraries were prepared using NEBNext ChIP-Seq Library Prep Master Mix Set and NEBNEXT Multiplex Oligos for Illumina.
