Cryo-Electron Microscopy, in combination with Tomography, has emerged as a new technology for visualizing molecular structures at a resolution beyond even 1 Å. Using this technology has revealed the native molecular details of membranes, viruses, and cells. This comprehensive, volume brings together authoritative overviews of these methods from structural and biological perspective. It is a must-have for researchers and graduate students, as well as those working in industry, primarily in the areas of biophysics, structural biology, crystallography and genomics. Key Features Focuses on the applications of cryo-EM to structural biology Documents the importance of cryo-EM/ET approaches in studying the structural determinants of cellular organelle and membrane protein biochemistry Reviews the applications of high-resolution structures of viruses Emphasizes structural insights of nuclear and gene machineries Includes a section will be focused entirely on the applications of cryo-EM/ET in drug discovery and therapeutic development
