library_construction_protocol: Cells were loaded on the Chromium Controller (10x Genomics). Single-cell RNA-seq libraries were prepared using the Chromium Single Cell 5′ v2 Reagent Kit (10x Genomics) according to manufacturer's protocol Libraries for transcriptome sequencing were constructed using 10x Chromium v2 5' reagents using standard protocols. Libraries for TCR sequencing were prepared from the same cDNA used in transcriptome sequencing using nested PCR as described in the associated publication. scRNA-seq + TCR-seq
