Summary:冷冻电子显微学具有悠久的历史,近年来随着硬件设备的革命性技术突破和软件算法方面技术发展,已经成为结构生物学领域最为重要的研究方法,也代表了未来的发展方向。其中,单颗粒三维结构重构法在最近的几年发展迅速,极大地拓展了研究方法的适用范围,并不断刷新所解析结构的高分辨率记录,成为结构生物学及相关学科最为激动人心的研究领域。本文将针对冷冻电子显微学发展的历史,近期革命性技术突破,以及复旦大学在该领域的布局和进展做简要介绍。
Bibliography:Cryo electron microscopy (cryo-EM) is one of the most important methods in structural biology. In the past five years, cryo-EM has milestone breakthrough due to revolutionary advances in hardware and methodology. The resolution has been pushed to as high as 1.8 A, which significantly extended the research scope of this method. Single particle reconstruction method has become one of the most exciting fields of structural biology and related subjects. Here we will briefly introduce the history of cryo-EM, recent revolutionary breakthrough, and the facility at Fudan University.
