The recent resolution revolution in cryo-electron microscopy has generated a huge interest in the technique for determining atomic resolution structures of large and dynamic macromolecular complexes that are intractable to crystallography and NMR. A key element of success in cryo-EM is the quality of the specimen vitrified on the cryo-EM grid. In this chapter we outline methods for cryo-EM grid sample preparation.
近期低温电子显微镜的分辨率革命引发了人们对该技术的极大兴趣,该技术可用于确定大型动态大分子复合物的原子分辨率结构,而这些结构用晶体学和核磁共振方法难以解决。低温电子显微镜成功的关键要素之一是在低温电子显微镜载网上玻璃化的样品质量。在本章中,我们概述了低温电子显微镜载网样品制备的方法。
