Abstract
Partially purified thrombosthenin with adenosine triphosphatase activity similar to that of actomyosin was subjected to electron microscopy. More than 50 percent of the material consisted of fibrils 80 to 100 angstroms in width. Occasional fibrils suggested a periodic structure. The morphology of isolated thrombosthenin resembled that of microfibrils in the cytoplasm and pseudopods of intact platelets.
摘要
将具有与肌动球蛋白相似的三磷酸腺苷酶活性的部分纯化的凝血酶原进行电子显微镜检查。超过50%的物质由宽度为80至100埃的纤维组成。偶尔可见的纤维显示出周期性结构。分离出的凝血酶原的形态与完整血小板的细胞质和伪足中的微纤维相似。
