Abstract
Myofibrils isolated from a variety of vertebrate muscle fibers have a set of peripheral filaments associated with the periphery of the Z line free to move away from the surface of the myofibril. Decoration with myosin subfragment 1 shows that these are actin filaments.
摘要
从多种脊椎动物肌纤维中分离出的肌原纤维有一组外周细丝，这些细丝与Z线的外周相连，可自由地从肌原纤维表面移开。用肌球蛋白亚片段1进行标记显示这些是肌动蛋白丝。
