Solutions such as correlated cryo-fluorescence light microscopy, [19] and super-resolution light microscopy (e.g. cryo-PALM [20]) can be integrated with cryoET. In these techniques, a sample containing a fluorescently-tagged protein of interest is plunge-frozen and first imaged in a light microscope equipped with a special stage to allow the ...
Cryogenic electron microscopy (cryo-EM) is a cryomicroscopy technique applied on samples cooled to cryogenic temperatures. For biological specimens, the structure is preserved by embedding in an environment of vitreous ice .
CryoTEM image of GroEL suspended in amorphous ice at 50 000 × magnification Structure of Alcohol oxidase from Pichia pastoris by CryoTEM. Transmission electron cryomicroscopy (CryoTEM), commonly known as cryo-EM, is a form of cryogenic electron microscopy, more specifically a type of transmission electron microscopy (TEM) where the sample is studied at cryogenic temperatures (generally liquid ...
This is useful for imaging specimens that would be volatile in high vacuum at room temperature. Cryo-STEM has been used to study vitrified biological samples, [33] vitrified solid-liquid interfaces in material specimens, [34] and specimens containing elemental sulfur, which is prone to sublimation in electron microscopes at room temperature.

Scanning electron cryomicroscopy (CryoSEM) is a form of electron microscopy where a hydrated but cryogenically fixed sample is imaged on a scanning electron microscope's cold stage in a cryogenic chamber.
Cryofixation is a technique for fixation or stabilisation of biological materials as the first step in specimen preparation for the electron microscopy and cryo-electron microscopy. [1] Typical specimens for cryofixation include small samples of plant or animal tissue , cell suspensions of microorganisms or cultured cells , suspensions of ...
A key factor in production of new technologies is whether it is cost effective and useful. Devices that make use of cryoelectronics and the applications of superconductivity such as computers, information transmission lines, and magnetocardiography have potential for commercial value outside of a few specific devices for singular purposes.
The EM Data Bank or Electron Microscopy Data Bank (EMDB) collects 3D EM maps and associated experimental data determined using electron microscopy of biological specimens.. It was established in 2002 at the MSD/PDBe group of the European Bioinformatics Institute (EBI), where the European site of the EMDataBank.org consortium is located.
