1:1 mixture of fresh frozen human HEK293T and mouse NIH3T3 cells obtained by 10x Genomics from ATCC were used in a classic experiment to demonstrate single cell behavior.
Libraries were generated from ~1630 cells (~500 cells recovered) as described in the Chromium Next GEM Single Cell 3' LT Reagent Kits (v3.1 Dual Index) User Guide (CG000399 RevB) using the Chromium Controller and sequenced on an Illumina NovaSeq 6000 to a read depth of 50k mean reads per cell.
Paired-end, dual indexing Read 1: 28 cycles (16 bp barcode, 12 bp UMI) i5 index: 10 cycles (sample index) i7 index: 10 cycles (sample index) Read 2: 90 cycles (transcript).
Run with --expect-cells=500.
