What can Cryo-EM do for you?

The Cryo-EM facility (RRID:SCR_026324), an MSU core, is a regional facility that brings state-of-the-art cryo-EM capabilities, including single particle analysis and cryo-electron tomography, to the Northern Rocky Mountains. Instrumentation includes i) a 200kV Talos Arctica transmission electron microscope with a Gatan K3 camera, ii) 120kV Tecnai Spirit, and iii) a Vitrobot Mark IV. Collectively, these instruments allow imaging of biological structures at single nanometer to 2 Å resolution, and thus enables 3D modeling of cells, viruses, proteins, nucleic acid, and other soft matter at the atomic level.

Access to the Montana State Cryo-EM Core Facility is available to internal MSU users, external academic users, and external commercial users.

Single Particle Analysis

The MSU Cryo-EM core routinely employs Single Particle Analysis (SPA) to determine high-resolution 3D structures of proteins and macromolecular complexes - in favorable cases approaching or surpassing 2Å resolution.  Importantly, current data collection rates can surpass 8,000 images/day.  The facility also offers live, on-the-fly data analysis, is equipped for full remote operation, and can transfer data between institutions via Globus.

Cryogenic Electron Tomography

Cryogenic Electron Tomography (CET) is a revolutionary technique that allows for high resolution 3D imaging of complex biological samples at single nanometer resolution, illuminating cellular and subcellular structures, organelles, liposomes, large macromolecular assemblies, virus-host interactions and viral assembly and trafficking.  In favorable cases sub-tomographic averaging can push structural information to sub-nanometer resolution.
