Record number: 1, Textual support number: 1 DEF
A form of transmission electron microscopy (EM) where the sample is studied at cryogenic temperatures (generally liquid nitrogen temperatures). 2, record 1, English, - cryo%2Delectron%20microscopy
Record number: 1, Textual support number: 1 CONT
The popularity of cryoelectron microscopy stems from the fact that it allows the observation of specimens that have not been stained or fixed in any way, showing them in their native environment, in contrast to X-ray crystallography, which generally requires placing the samples in non-physiological environments, which can occasionally lead to functionally irrelevant conformational changes. 2, record 1, English, - cryo%2Delectron%20microscopy

Microscopie électronique à transmission dans laquelle l'échantillon est refroidi à des températures cryogéniques (celles de l'azote liquide). 2, record 1, French, - cryomicroscopie%20%C3%A9lectronique
Record number: 1, Textual support number: 1 OBS
Utilisée surtout pour des échantillons biologiques. Ceux-ci sont placés en solution aqueuse afin d'être vitrifiés (refroidissement rapide qui permet d'éviter la cristallisation). Cette technique permet de conserver la structure tridimensionnelle native des molécules biologiques. 2, record 1, French, - cryomicroscopie%20%C3%A9lectronique
Record number: 1, Textual support number: 2 OBS
Les images obtenues peuvent être utilisées pour calculer une structure 3D de l'échantillon. 3, record 1, French, - cryomicroscopie%20%C3%A9lectronique
