Design and synthesis of an antigenic mimic of the Ebola glycoprotein

An antigenic mimic of the Ebola glycoprotein was synthesized and tested for its ability to be recognized by ail anti-Ebola glycoprotein antibody. Epitope-mapping procedures yielded a suitable epitope that, when presented oil the surface of I nanoparticle, forms a Structure that Is recognized by an antibody specific for the native protein. This mimic-antibody interaction has been quantitated through ELISA and QCM-based methods and yielded all affinity (K-d = 12 x 10(-6) M) within two orders of magnitude of the reported affinity of the native Ebola glycoprotein for the same antibody. These results suggest that the rational design approach described herein is a Suitable method for the further development of protein-based antigenic mimics with potential applications in vaccine development and sensor technology.
