COMPOSITIONS, METHODS, AND KITS FOR ENHANCING THE IMMUNOGENICITY OF PATHOGENIC ANTIGENS

摘要

The invention provides a method of enhancing the immunogenicity of pathogenic antigens by removing or disrupting intrachain disulfide bonds responsible for maintaining tertiary protein structure. Removal of one or more disulfide bonds can increase the titer of neutralizing antibodies to a pathogen (e.g., a bacterium, fungus, virus, or parasite). The invention also features vaccines, expression vectors, and methods for the manufacture and use thereof.
