Nuclei were isolated from sorted cells using a solution of 10 mM Tris-HCl pH 7.4/10 mM NaCl/3 mM MgCl2/0.1% IGEPAL CA-630. Immediately following isolation, the transposition reaction was conducted using Tn5 transposase and TD buffer (Illumina) for 30 minutes at 37 °C. Transposed DNA fragments were purified using a Qiagen MinElute Kit, barcoded, and PCR amplified for xx cycles using NEBNext High Fidelity 2x PCR master mix (New England Biolabs), and then the libraries were purified with AMPure XP beads.
