RNA was extracted from both GFP-positive and GFP-negative cell fractions using miRNAeasy Mini Kit (#217004, Qiagen). Ribosomal RNA was depleted, and total RNA was captured from the RNA samples using Illumina TruSeq Stranded RNA LT kit Ribo-ZeroTM Gold (# 15032619, Illumina). For tagmentation, cell nuclei were incubated with 2.5 UL enzyme in 50UL total volume at 37°C in a thermocycler (Illumnia Nextera DNA library prep kit, #FC1211030). DNA was cleaned up using MinElute PCR purification kit (#28006, Qiagen) and eluted in 10UL of EB buffer. Flow-sorted RNA samples were sent to the Deep Sequencing and Microarray Core (Johns Hopkins University) for library preparation and sequencing. Around 8-10 libraries were pooled and sequenced for paired-end 75 cycles using the NextSeq 500 system with ~400-500 million reads per run, resulting in ~45-55 million reads per library. Sorted cells (~50k-75k) from GFP-positive samples were used for ATAC library preparation. Completed ATAC-Seq libraries were then analyzed by Fragment Bioanalyzer and sequenced for paired-end 75 cycles using the NextSeq 500 system with ~400-500 million reads per run.
