Anti-α-actinin IgG showed immune reactivity against not only α-actinin in ordinary muscle but also papain-digests of the α-actinin. According to immunoelectron microscopic method, α-actinin was detected on Z line of ordinary muscle cells and non-specific reactions were not detected on another organelles. The changes of α-actinin in the ordinary muscle of cultured red sea bream during storage in ice were examined by SDS-PAGE followed by its immunoblotting. It was found that the limited digestion of α-actinin in ordinary muscle of cultured red sea bream started on day one in ice, then, native α-actinin was not detected on day 5 and 7. These results suggested that the weakening of Z-disks in ordinary muscle was caused by the disappearance of α-actinin and resulted in the softness of the flesh texture of cultured red sea bream., 日本水産学会誌 = Bulletin of the Japanese Society of Scientific Fisheries. 2001, 67(4), p.723-727}, pages = {723--727}, title = {養殖マダイの氷蔵中における普通筋中 α-アクチニンの限定分解}, volume = {67}, year = {2001} }
