High-resolution single-particle cryo-EM of samples vitrified in boiling nitrogen
IUCrJ, 2021 Based on work by Dubochet and others in the 1980s and 1990s, samples for single-particle cryo-electron microscopy (cryo-EM) have been vitrified using ethane, propane or ethane/propane mixtures.

Oxygen-Sensitive Metalloprotein Structure Determination by Cryo-Electron Microscopy
Biomolecules, 2022 Metalloproteins are involved in key cell processes such as photosynthesis, respiration, and oxygen transport. However, the presence of transition metals (notably iron as a component of [Fe-S] clusters) often makes these proteins sensitive to oxygen ...
