Abstract

Observation with a phase-contrast microscope clearly shows that melting of an A-band, i.e., a bundle of thick (myosin) filaments, in a rabbit skeletal myofibril occurs from both ends in the pressure of high concentrations of KCl and PPi. Thick filaments partially melted from both ends can be obtained in a myofibril.

摘要

用相差显微镜观察清楚地表明，在高浓度氯化钾和焦磷酸存在的情况下，兔骨骼肌肌原纤维中的A带（即一束粗（肌球蛋白）丝）从两端开始发生熔化。在肌原纤维中可以获得从两端部分熔化的粗丝。
