Adjuvants in vaccine formulations are designed to enhance immune responses against a target antigen or pathogen. The ability of these vaccines to induce activation and differentiation of mature naïve B cells to produce pathogen-specific antibodies (immunoglobulins; Ig) helps guarantee long-lived humoral immunity. This process involves clonal expansion of antigen-specific B cells, genomic rearrangement of Ig heavy (IgH) and light (IgL) loci, somatic hypermutation (SHM), and clonal selection for affinity-matured antibody, resulting in a vast but directed repertoire of B cells expressing highly specific antibody proteins. High-throughput sequencing of the IgH and IgL complementary determining regions (CDRs) derived from various B cell populations provides an unprecedented way to observe dynamic responses of the humoral immune repertoire in response to vaccination. However, applying high-throughput sequencing (HTS) methodologies to multi- armed in vivo experiments requires careful coordination of sample preparation with downstream bioinformatics, particularly with regard to issues of quantitation, sequence fidelity, bar-coding, and multiplexing strategies. Here, we overview strategies of high-throughput sequencing and analysis of the adaptive immune complex loci applied to multi-armed, multiplexed experiments.
