Developments in cryo-electron microscopy are creating new opportunities within structural biology and there is currently great interest in developing cryo-EM as a core tool for atomic level structural biology. Many structural techniques can give atomic or near atomic level information, but lack the ability to study proteins within a near-native environment, for example within a cellular compartment. Cryo-EM provides this opportunity, but despite the recent massive improvements in single particle cryo-EM, obtaining sub-2Å structural information is still a major challenge. Cryo-electron microscopy has undergone significant developments in microscope design, camera technology and data processing regimes, but there are significant challenges that remain and opportunities to explore, many of which must be tackled by the community as a whole, rather than by individual groups. For example, sample preparation is central to electron microscopy and is currently a significant bottleneck in many experiments, and there are significant problems with ensuring the integrity of the field in terms of dealing with inherently low signal-to-noise images. This volume brings together leading researchers from the UK and the international cryo-electron microscopy community to discuss current developments and new challenges in the field. In this volume the topics covered include: Sample preparation in single particle cryo-EM ; Pushing the limits in single particle cryo-EM ; Tomographic analysis, CLEM ; Map/model validation and machine learning in EM.

To preserve tissue by freezing is an ancient concept going back pre sumably to the practice of ice-age hunters. At first glance, it seems as simple as it is attractive: the dynamics of life are frozen in, nothing is added and nothing withdrawn except thermal energy. Thus, the result should be more life-like than after poisoning, tan ning and drying a living cell as we may rudely call the conventional preparation of specimens for electron microscopy. Countless mishaps, however, have taught electron microscopists that cryotechniques too are neither simple nor necessarily more life-like in their outcome. Not too long ago, experts in cryotechniques strictly denied that a cell could truly be vitrified, i.e. that all the solutes and macro molecules could be fixed within non-crystalline, glass-like solid water without the dramatic shifts and segregation effects caused by crystallization. We now know that vitrification is indeed pos sible. Growing insight into the fundamentals of the physics of water and ice, as well as increasing experience of how to cool cells rapidly enough have enlivened the interest in cryofixation and pro duced a wealth of successful applications.

Electron cryomicroscopy, is a form of transmission electron microscopy (EM) where the sample is studied at cryogenic temperatures (generally liquid nitrogen temperatures). Cryo-EM is developing popularity in structural biology. This volume from the Advances in Protein Chemistry and Structural Biology series is Part B and covers essential topics.

This volume, along with Part A and Part B, is dedicated to a description of the instruments, samples, protocols, and analyses that belong to cryo-EM. It emphasizes the relatedness of the ideas, instrumentation, and methods underlying all cryo-EM approaches, which allow practitioners to easily move between them. Within each section, the articles are ordered according to the most common symmetry of the sample to which their methods are applied. Includes time-tested core methods and new innovations applicable to any researcher Methods included are useful to both established researchers and newcomers to the field Relevant background and reference information given for procedures can be used as a guide
