library_construction_protocol: Cells grown on 10 cm plates in culture  were fixed in 1% formaldehyde, scraped into collection tubes, and then prepared using the Hi-C (Rao et. al. 2014) or HiChIP (Mumbach et. al. 2016) protocols. Libraries were constructed using Illumina tn5 transposase on HiC and HiChIP interaction libraries followed by PCR amplification using a multiplex bar-coded PCR primer set.
