Multi-body refinement in Relion allows high-resolution reconstruction and visualisation of molecular motions in cryo-EM single-particle data sets with continuous forms of structural heterogeneity. Radiation damage in single-particle cryo-electron microscopy: effects of dose and dose rate. Manikandan Karuppasamy,a‡2Fatemeh Karimi Nejadasl,a‡ Milos 

When the electron beam interacts with the specimen, it loses energy by a variety of mechanisms. The lost energy is converted into alternative forms such as heat, emission of low-energy secondary electrons and high-energy backscattered…

Building on previous work in cryo-electron microscopy (Entchev et al, 2015), it shown that a combination of the Volta phase plate and a small amount of defocus can simplify the experimental set-up, increase the data acquisition rate and… Chen 2018 - Read online for free. Articulo In cryo-electron microscopy, resolution is typically measured by the Fourier shell correlation (FSC), a three-dimensional extension of the Fourier ring correlation (FRC), which is also known as the spatial frequency correlation function.

Patwardhan, “Single-particle electron cryo-microscopy: towards atomic resolution,” Quart. Here, we established a system for studying HIV-1 virus-like particle assembly and release by cryo electron tomography of intact human cells. In the research arena, modalities such as immunoelectron microscopy, cryo-electron microscopy, and electron tomography have demonstrated how viral structural components fit together, attach to cells, assimilate during replication, and… Immunogold particle detection is a time-consuming task where a single image containing almost a thousand particles can take several hours to annotate. In this work we present a framework for the.

The site includes a brief introduction to the transmission electron microscope, and more detailed information on preparation of biological sections using grids, staining and freezing and Single Particle Reconstruction.

We showed that cryo-SOFI, in comparison with conventional cryo-FM, is especially powerful for imaging structures in thicker parts of the cell due to its ability to suppress out-of-focus signals, thus achieving optical sectioning. Cryo-ET data were collected with single-axis tilt using either a Tecnai F20 transmission electron microscope (FEI) equipped with an Eagle 4K × 4K multiport CCD camera (FEI), or a Titan Krios (FEI) with a K2 Summit direct electron detector… Wave – Particle Duality The accelerating electrons explains the wave – particle duality of the electrons and photons, since the elementary charges are distributed on delta x position with delta p impulse and creating a wave packet of the… The site includes a brief introduction to the transmission electron microscope, and more detailed information on preparation of biological sections using grids, staining and freezing and Single Particle Reconstruction. Here we present the cryo-electron microscopy (cryo-EM) structure the membrane, with S1 extending about 18 Å into the lysosomal lumen

In electron cryo-microscopy (cryo-EM), the electron beam that is used for imaging also causes the sample to move. This motion blurs the images and limits the resolution attainable by single-particle analysis.

Cryo-ET data were collected with single-axis tilt using either a Tecnai F20 transmission electron microscope (FEI) equipped with an Eagle 4K × 4K multiport CCD camera (FEI), or a Titan Krios (FEI) with a K2 Summit direct electron detector… Wave – Particle Duality The accelerating electrons explains the wave – particle duality of the electrons and photons, since the elementary charges are distributed on delta x position with delta p impulse and creating a wave packet of the… The site includes a brief introduction to the transmission electron microscope, and more detailed information on preparation of biological sections using grids, staining and freezing and Single Particle Reconstruction.

Structural insights into the architecture and functional properties of zebrafish TRPC4 are revealed by high-resolution cryo-EM. Single particle analysis is a group of related computerized image processing techniques used to analyze images from transmission electron microscopy (TEM). These methods were developed to improve and extend the information obtainable from… Atomic resolution models for proteins and protein complexes are usually obtained using X-ray crystallography or NMR spectroscopy, and in selected instances, by cryo-electron microscopy (cryo-EM) of ordered protein assemblies. We showed that cryo-SOFI, in comparison with conventional cryo-FM, is especially powerful for imaging structures in thicker parts of the cell due to its ability to suppress out-of-focus signals, thus achieving optical sectioning.
