Аннотация
Epitopes on envelope glycoprotein of Indian strain of Japanese encephalitis virus were delineated by prediction methods. Monoclonal antibodies (MAb) raised against a putative B cell epitope peptide, reacted with the virion in ELISA and immunofluorescence assays. One MAb was also able to neutralize the virus. The reactivity of this MAb against a Sri Lankan strain was checked, since this strain had a substitution within the B cell epitope at position Egp 153 (G-->W). The MAb was able to bind to, but was not able to neutralize the Sri Lankan isolate. The data indicated that the predicted B cell epitope is a neutralizing epitope and may be included in a peptide-based vaccine against the virus.
