原子力显微镜 (AFM) 用于表征网格蛋白 triskelia 的结构和相互作用。停留在云母表面上的单个湿三轮虫的时间序列图像清楚地表明了三轮虫的构象波动。干燥样品的 AFM 产生的图像具有纳米分辨率,与通过阴影样品的电子显微镜获得的图像相当。当将 triskelia 浸入低盐、低 pH 缓冲液中时,观察到 triskelion 二聚体和组装中间体的数量增加,以及尺寸与网格蛋白笼相似的结构。这些实体已通过 AFM 蛋白质体积计算进行了量化。
Atomic force microscopy (AFM) is used to characterize the structure and interactions of clathrin triskelia. Time sequence images of individual, wet triskelia resting on mica surfaces clearly demonstrate conformational fluctuations of the triskelia. AFM of dried samples yields images having nanometric resolution comparable to that obtainable by electron microscopy of shadowed samples. Increased numbers of triskelion dimers and assembly intermediates, as well as structures having dimensions similar to those of clathrin cages, are observed when the triskelia were immersed in a low salt, low pH buffer. These entities have been quantified by AFM protein volume computation.
