Biotin-labeled protein-A enzyme-linked immunosorbent assay for the detection of Japanese encephalitis antibody in sera from humans, swine and several animal species.
Biotin-labeled protein-A was incorporated into enzyme-linked immunosorbent assay (ELISA) for seroepidemiological surveys of Japanese encephalitis (JE) virus infection in several vertebrates. The ELISA could detect the JE antibody in sera from man, rhesus monkey, swine, horse, dog, rabbit and mouse by the same reagent, but not in sera from cattle and pigeon. The titers of ELISA antibody were almost the same as those of 2-ME resistant HI antibody. Since non-specific reaction in ELISA was very low in the sera of swine and humans, the cut-off titer for the assay could be set at 1:5 for positive antibody.
