Cryo Electron Microscopy of TRP Channels

2019
Cryo electron microscopy (cryo-EM) is a powerful technique that can be used to elucidate the structural architecture of a protein molecule in a physiologically relevant environment. In this method, purified protein is frozen in its aqueous buffer in a thin layer of vitreous ice in which the biological macromolecules are embedded in various orientations.

Cryo-electron Microscopy of Vitreous Sections

2013
More than 30 years ago two groups independently reported the vitrification of pure water, which was until then regarded as impossible without a cryoprotectant [1, 2]. This opened the opportunity to cryo-electron microscopy (cryo-EM) to observe biological samples at nanometer scale, close to their native state. However, poor electron penetration through

Visualisation of the actin cytoskeleton by cryo-electron microscopy

Journal of Cell Science, 2002
An understanding of the mechanisms driving cell motility requires clarification of the structural organisation of actin filament arrays in the regions of cell protrusion termed lamellipodia. Currently, there is a lack of consensus on lamellipodia organisation stemming from the application of alternative procedures for ultrastructural visualisation of ...

Cryo-Electron Microscopy of DNA

1994
Seeing is believing! Less than 10 years after the discovery of the double helical structure of the DNA, the development by Kleinschmidt and Zahn (Kleinschmidt and Zahn 1959) of a method for direct visualization of nucleic acids has been and remains one of the major achievement of electron microscopy.

Grid Preparation for Cryo-Electron Microscopy

2012
Once 2D crystals suitable for electron crystallography have been obtained, grid preparation for cryo-EM is a critical step in obtaining high-resolution structural information. Specimens have to be prepared in a manner that prevents dehydration and disruption of the crystals in the vacuum of the electron microscope.

Cryo-electron microscopy of myelin treated with detergents

Cell and Tissue Research, 1994
After detergent extraction, myelin lamellae disaggregate into diverse globular fragments that correspond to the globular structures observed in normal cryofixed myelin. The interaction of these structural units in the bilayer is probably the morphological basis that provides the stability of the myelin lamellae and their lamination.
