What is Cryo-Electron Microscopy? Essentially, Cryo-electron microscopy (Cryo-EM) is a type of transmission electron microscopy that allows for the specimen of interest to be viewed at …

Low-temperature scanning electron microscopy (cryoSEM) was introduced in the early 1970s, shortly after the appearance of the first commercial scanning electron microscopes. This …

Combining CSEM with quantitative energy dispersive X-ray microanalysis of the cryo-fixed specimens (CEDX) allows cell-specific localization of elements heavier than atomic number …

Typical usage: A wide range of samples, from small (∼150 kDa) macromolecules to whole eukaryotic cells can be vitrified and imaged by cryo-EM. Advantages: Sample is visualised in a …
