Targeted enrichment of TCRs from a fresh surgical resection of a squamous non-small cell lung carcinoma tumor.
The same cDNA was used to generate gene expression (vdj_v1_hs_nsclc_5gex) and B cell Ig (vdj_v1_hs_nsclc_b) specific libraries.
Libraries were prepared following the Single Cell V(D)J Reagent Kits User Guide (CG000086 Rev C).
- ~15,000 cells loaded
- 2,235 expected TCR-expressing cells recovered (based on CD3D/CD3E expressing fraction in the gene expression data)
- 2,012 cells detected with either single TRA or TRB or both
- 1,538 cells with productive V-J spanning (TRA, TRB) pair
- Sequenced on an Illumina NovaSeq 6000 with NovaSeq software v1.2 with ~21,000 read pairs per cell
- 150bp read1 (including 16bp Chromium barcode, 10bp UMI, 13bp switch oligo and transcript), 150bp read2 (transcript), and 8bp i7 sample barcode read configuration
