β¦ Synopsis
CryoEM can be divided into three different sub-disciplines: electron crystallography where the macromolecules are arranged periodically into thin crystals, single particle cryoEM of randomly oriented isolated macromolecular assemblies and electron tomography of vitreous specimens containing objects in situ or in isolated form but being reconstructed individually. These methods provide a comprehensive, complementary approach of transmission electron microscopy (TEM) for studies of biological structure reaching from the atomic to the cellular level.

We describe a temperature-jump device that permits time-resolved studies of thin cryo-transmission electron microscopy specimens. The specimen is rapidly heated to induce a change in microstructure just prior to cryo-fixation. The apparatus consists of a xenon arc lamp equipped with a shutter contro
**An insight into the molecular assembly processes** that lead ultimately to the gelation of water by small organic molecules can be gained by the combination of two powerful techniques. Vitrified ice cryoβtransmission electron microscopy (TEM) (see Figure) and Xβray diffraction, have been applied t
