Next-generation sequencing has been applied to understand the diversity of the variable regions of heavy (VH) and light chains (VL) that determine the antigen specificity of antibodies. The heavy and light chains are encoded in separate gene loci, and each B cell normally expresses a single functional heavy and light chain sequence. A mature antibody consists of two identical heavy chains linked through disulphide bonds and two identical light chains each linked to one of the heavy chains, generating two identical antigen-binding sites formed by the first immunoglobulin domain of each chain pair 2. Somatic hypermutation (SHM) and class switching add to antibody diversity. B cells produce a diverse array of antibodies by rearranging variable, diversity, and joining immunoglobulin germline gene segments 1, 2, 3. Our results establish scBCR-seq as a powerful tool for antibody discovery.Īntibody diversity is an important feature of the adaptive immune system. We synthesized, expressed and tested 93 clones from the identified lineages and found that 99% ( n = 92/93) of the clones were antigen-reactive. Importantly, scBCR-seq identified an additional 710 candidate lineages not recovered as hybridomas. The scBCR-seq data recovered 81% ( n = 56/69) of B-cell lineages identified from hybridomas generated from the same set of B cells subjected to scBCR-seq. In addition, we immunized rats with chicken ovalbumin and profiled antigen-reactive B cells from lymph nodes of immunized animals. We sequenced more than 250,000 B cells from rat, mouse and human repertoires to characterize their lineages and expansion. Here we use high-throughput single-cell B-cell receptor sequencing (scBCR-seq) to obtain accurately paired full-length variable regions in a massively parallel fashion. It does not store any personal data.Obtaining full-length antibody heavy- and light-chain variable regions from individual B cells at scale remains a challenging problem.

Its headquarters are located in Pleasanton, California. is an American company incorporated in 2012 that develops and manufactures integrated systems for whole genome sequencing, exome sequencing and single cell transcriptomics. Where is 10x Genomics located?ġ0x Genomics, Inc. The individual gel barcodes are delivered to each cell via flow-cytometry, where each cell is fed single-file along a liquid tube and tagged with a 10X gel bead. The 10X barcoded gel beads consist of a pool barcodes which are used to separately index each cell’s transcriptome. This helps to understand the complex immune system and propose new targets for disease treatment. Single-cell sequencing technologies can detect individual immune cells, thereby distinguishing different groups of immune cells, as well as discovering new immune cell populations and their relationships (Fig. Users can set up and run Cell Ranger pipelines through Cloud Analysis.
