BCR and neoplasm: To elucidate the heterogeneity of tumour immune cell infiltration, we performed single cell RNAseq (gene expression, GEX), ADT-seq (cell surface protein expression derived from Antibody-Derived Tags), B cell receptor (BCR) and T cell receptor (TCR) sequencing on CD45+ cells enriched from matched fresh tumour tissue following surgical resection of 12 treatment-naïve patients and matched PBMCs, herein referred to as PancrImmune.
