library_construction_protocol: 4C experiments were performed as described (Krijger et al., 2020). Eight to ten million cells were cross-linked with formaldehyde. DNA was digested in situ with Csp6I (first cutter) and NlaIII (second cutter). Indexed Illumina sequencing adapters were introduced to ligation fragments of interest with a two-step PCR strategy as described in Krijger et al., 2020.
