Immunoglobulin isotype, domain specificity, and cross-reactivity to WNV (W) and ZIKV (Z) were determined by ELISA. “N” indicates no binding to either WNV (W) or ZIKV (Z) recombinant E protein or JEV E protein domains.
Purified MAb was incubated with 102 FFU of the indicated JEV strain of genotypes GI to GIV for 1 h at 37°C. Fifty percent FRNT (FRNT50) values were determined by nonlinear regression. Results are the average from three independent experiments performed in triplicate.
