Patent ID: 10746742

Abstract:
Disclosed herein are methods of high-throughput mapping of viral neutralizing antibody epitopes. Also disclosed are in vitro immunoprecipitation-based adenoassociated virus Barcode-Seq-based methods of mapping viral neutralizing antibody epitopes. In some embodiments, a method of high-throughput mapping of viral NtAb conformational epitopes can be utilized, which may comprise HP scanning of mutant viral libraries, immunoprecipitation (IP), and/or next-generation sequencing (NGS) technology. In some embodiments, a method of identifying one or more dominant epitopes in a viral vector may comprise contacting a mutant capsid of a virus with serum from a subject previously exposed to the virus and immunopredpitating serum immunoglobulins from the serum. In various embodiments, the viral vector may be an AAV vector.
