Electron cryotomography can be used to solve the three-dimensional structures of individual large macromolecules, assemblies, and even small intact cells to medium (approximately 4-8 nm) resolution in a near-native state, but restrictions in the range of accessible views are a major limitation. Here we report on the design, characterization, and(More)
Electron cryotomography is the highest-resolution structural technique currently available that can be applied to unique objects such as flexible large protein complexes, irregular viruses, organelles and small cells. Specimens are preserved in a near-native, 'frozen-hydrated' state by vitrification. The thickness of the vitreous ice must be optimized for(More)
