10,000 sorted cells from each population were pelleted and resuspended in 2x Tagmentation Buffer (Illumina), 0.02% Digitonin, and 0.1% Tween-20, with Tagment DNA TDE1 Enzyme (Illumina) and incubating at 37°C for one hour.  The mix was then incubated with proteinase K for 30 minutes at 40°C. High molecular weight DNA was removed with a 0.7x selection ratio of Agencourt AMPureXP beads (Beckman Coulter) and low molecular weight DNA was isolated from the remainder with a 1.2x selection ratio. Library amplification was performed with KAPA HiFi HotStart ReadyMix (KAPA) and i5 and i7 indexing primers (Nextera DNA CD Indexes) for 11-15 total cycles depending on the sample concentration reached after 5 cycles (KAPA Library Quantification kit). Library DNA was purified with a 1x selection ratio of AMPureXP beads. The final library was verified by High Sensitivity DNA Bioanalyzer (Agilent).
