WebAbstract. Transmission electron cryo-microscopy (cryoEM) is a versatile tool in the structural analysis of proteins and biological macromolecular assemblies. In this review, we present a brief survey of the methods used in cryoEM, and their current developments. These latest advances provide exciting opportunities for the three-dimensional ... WebSince 2013, cryogenic electron microscopy (cryo-EM) single particle analysis (SPA) has become a mainstream means for high-resolution structural elucidation of MPs ( 10, 11 ). Multiple reagents have been applied to “solubilize” the MPs to single particles for analysis.
