Automated Identification of Filaments in Cryoelectron Microscopy Images
Journal of Structural Biology, 2001Since the foundation for the three-dimensional image reconstruction of helical objects from electron micrographs was laid more than 30 years ago, there have been sustained developments in specimen preparation, data acquisition, image analysis, and interpretation of results.

Lipidic spherulites: Formulation optimisation by paired optical and cryoelectron microscopy
European Journal of Pharmaceutics and Biopharmaceutics, 2013Objective of this study was to assess the various steps leading to spherulite obtention by means of optical and cryoelectron microscopy. The formulation, resting and hydration steps were optimised. Green-based process and organic-based process were compared.

3-D reconstruction of bluetongue virus tubules using cryoelectron microscopy
Journal of Structural Biology, 1992Bluetongue virus (BTV) forms tubules in infected mammalian cells. These tubules are virally encoded entities which can be formed with only one protein, NS1. The NS1 protein does not form a part of virus particles, and its function in viral infection is uncertain.

Quick‐Frozen Microtubules Studied by Cryoelectron Microscopy and Image Processing
Annals of the New York Academy of Sciences, 1986Frozen-hydrated microtubules have been studied by cryoelectron microscopy. We have described some structural features of microtubules, their relationship with the computed or X ray diffraction patterns, and the influence of the contrast transfer function.

Three-dimensional reconstruction of Limulus polyphemus hemocyanin from cryoelectron microscopy
Journal of Molecular Biology, 1997Hemocyanin (Hc) the respiratory pigment of the horseshoe crab Limulus polyphemus (Lp) is composed of 48 approximately 75 kDa copper-containing subunits arranged in eight hexameric groups. In this study, we used the random conical tilt series method to do a three-dimensional (3D) reconstruction of Lp Hc observed in vitreous ice.

Cryoelectron Microscopy of Frozen-Hydrated Pyruvate Dehydrogenase Complexes
Proceedings, annual meeting, Electron Microscopy Society of America, 1990Pyruvate dehydrogenase complexes (PDC’s) from both prokaryotes and eukaryotes exist as large multisubunit assemblies in which one of the component enzymes, dihydrolipoyl transacetylase (E2), forms a structural core that possesses multiple binding sites on its surface for the pyruvate dehydrogenase (E1) and dihydrolipoyl dehydrogenase (E3) components ...

Cryoelectron microscopy: from molecules to systems
2008Cryo electron microscopy is a generic term referring to different imaging modalities as applied to samples embedded in vitreous ice. Thereby it combines a close-to-life preservation of biological materials with the potential of high-resolution threedimensional imaging [1].

Structural Studies of Ca2+-ATPase by Cryoelectron Microscopy
1994The Ca2+-ATPase from sarcoplasmic reticulum (SR) is exceedingly well characterized in terms of kinetics, ligand binding and amino acid sequence. For example, particular events in the reaction cycle have been assigned to specific amino acid residues by sitedirected mutagenesis and characterization of ligand binding.
