BCR + GEX Tutorial Dataset: Single-cell BCR and gene expression data from tumor-draining lymph node and primary tumor of an ovarian cancer patient

Analysis-ready single-cell BCR and gene expression data from one ovarian cancer patient, used in the BCR + GEX Integration Tutorial. The dataset includes paired lymph node (P1_LN) and primary tumor (P1_PT) samples from the same patient, originally published in Nathan et al. (2026, Immunity). Files include Cell Ranger GEX output (.h5), BCR sequence data (AIRR-format TSV), processed BCR data (bcr_data.tsv), and an annotated integrated Seurat object (RDS). These files serve as input and checkpoint files for the three-part tutorial hosted here. Raw sequencing data are available on GEO under accession GSE319733.
