library_construction_protocol: Monocytes and macrophages were rinsed in PBS, and resuspended in PBS containing 2% FBS and 1 mM EDTA. H3K27ac chromatin immunoprecipitation (ChIP) was performed using anti-H3K27ac polyclonal antibody (Diagenode, C15410196) and iDeal ChIP-seq kit for Histones (Diagenode, C01010051).  10^6 cells per sample. Library preparation was performed using the Ovation Ultralow DNA-seq library preparation kit and libraries were sequenced on the IlluminaNovaSeq 6000 instrument generating an average of 30 million reads per sample.
