Structural polypeptides were analyzed by polyacrylamide gel electrophoresis. A2 and Nakayama-NIH strains were found to possess specific antigens in addition to common antigens. However, Mie 44-1 and A2 were found to have almost the same antigenicity. Hemagglutinins of A2, P3 and Nakayama-NIH showed optimum pH at 6.4 or lower and stable for heating at 37℃. JaGAr-01 strain possessing optimum pH at 6.8 or higher was unstable for heating. In spite of these biological and immunological differences, analysis of the structural polypeptides by polyacrylamide gel electrophoresis showed no difference., 熱帯医学 Tropical medicine 23(1). p23-31, 1981}, pages = {23--31}, title = {日本と中国から分離された日本脳炎ウイルス株の免疫学,生物学と生化学性質の比較研究.}, volume = {23}, year = {1981} }
