From structure to sequence: Antibody discovery using cryoEM. 2022-01, Science advances, Vol. 8, p. eabk2039<br /> <br /> == Abstract ==<br /> <br /> One of the rate-limiting steps in analyzing immune responses to vaccines or infections is the isolation and characterization of monoclonal antibodies. Here, we present a hybrid structural and bioinformatic approach to directly assign the heavy and light chains, identify complementarity-determining regions, and discover sequences from cryoEM density maps of serum-derived polyclonal antibodies bound to an antigen. When combined with next-generation sequencing of immune repertoires, we were able to specifically identify clonal family members, synthesize the monoclonal antibodies, and confirm that they interact with the antigen in a manner equivalent to the corresponding polyclonal antibodies. This structure-based approach for identification of monoclonal antibodies from polyclonal sera opens new avenues for analysis of immune responses and iterative vaccine design. <br /> <br /> == Keywords ==<br /> <br /> == Links ==<br /> <br /> https://www.science.org/doi/10.1126/sciadv.abk2039?url_ver=Z39.88-2003<br /> <br /> == Related software ==<br /> <br /> == Related methods ==<br /> <br /> == Comments ==</div>
