library_construction_protocol: Live cells (typically ~50,000) were pelleted and tagmentation was performed at 37ºC for 30min as described in (Buenrostro et al., 2013). Briefly, cell pellets were resuspended in buffer containing Tn5 Transposase (Nextera DNA Sample Preparation kit; Illumina), incubated at 37ºC for 30min, and DNA was isolated using the MinElute PCR purification kit (Qiagen). Tagmented DNA was PCR-amplified for 10 cycles and purified using AMPure XP magnetic beads (Beckman Coulter). Double-sided AMPure cleanup to remove high-molecular-weight fragments was conducted by incubation of double-concentrated AMPure beads added at 0.55x volume to the PCR reactions, followed by cleanup with a 1x AMPure volume. Sequencing libraries were pooled and sequenced on a HiSeq 2500 instrument.
