| Research Abstract |
To identify novel malaria vaccine candidates, we first obtained serum samples from the children enrolled in the malaria cohort study in Papua New Guinean. We then established a micro-scale immunoscreening system for high-throughput detection of antigen-antibody reaction. Genome-widely expressed 1,900 parasite proteins by the wheat germ cell-free system covering one-third of the parasite genome were screened by using the immunoscreening system. As a result of the preliminary screening, we identified 650 immunoreactive proteins with the malaria immune serum samples which we previously had enough amount. The result suggests that this screening system would be effective to discover novel malaria vaccine candidates by using Papua New Guinean serum samples.
