Using the Chromium Single Cell 3′ Reagent Kit v3User Guide, single cell suspensions were partitioned into nanoliter droplets called Gel-bead-in-Emulsions (GEMs) to achieve single cell resolution. The cDNA generated within each individual GEM is tagged with a common 16nt 10x barcode and a 12nt unique molecular barcode during the RT reaction. Purified cDNA was amplified for 11 cycles before being purified using SPRIselect beads. Samples were then run on a Agilent Bioanalyzer to determine cDNA concentration. 10uL of purified cDNA was used to generate the Illumina library for sequencing. For sample preparation on the 10x Genomics platform, the Chromium Single Cell 3′ GEM, Library & Gel Bead Kit v3 16 rxns (PN-1000075), Chromium Chip B Single Cell Kit, 48 rxns (PN-1000073) and Chromium i7 Multiplex Kit (PN-120262) were used. The single cell libraries were then sequenced on the Illumina NovaSeq 6000 S4 200 cycle flow cell generating 28x98 reads. A median sequencing depth of 50,000 reads/cell was targeted for each sample.
