V(D)J recombination occurs in lymphocytes when T and B cells assemble variable (V), diversity (D), and joining (J) gene segments, contributing to the generation of receptors that recognize and respond to perturbations. V(D)J recombination produces clones of unique T cell receptor (TCR) chains or B cell receptor (BCR) chains giving rise to the diverse repertoire of T and B cell populations which are imperative to adaptive immune system function¹. The frequency of generated clones can be measured and explored, giving researchers a powerful view into variation, expansion, and diversity within the biological system. You can import filtered Contig Annotation CSV files² from the 10X 10x Genomics Cell Ranger V(D)J or multi pipeline³. If there is matching gene expression data, it can also be imported and analyzed within the same project. We recommend uploading the filtered feature barcode matrices as either the Hierarchical Data Format (H5 or HDF5)⁴ or Market Exchange Format (MEX)⁵.
