Facility Overview

The Center for Structural Biology Cryo-Electron Microscopy Facility houses ThermoScientific cryo transmission electron microscopes for high resolution data collection of biological specimens by tomography and single-particle analysis.

The Titan Krios G4 is the state-of-the-art 300kV microscope that combines equipment stability, enhanced automation and advanced software to aid researchers in efficient data collection. This microscope is equipped with a Volta phase plate, Gatan’s BioQuantum energy filter, K3 and Falcon3 direct electron detector (DED) cameras and is computationally supported by multiple GPU workstations and a local 600TB RAID system. The Glacios 200 kV microscope is equipped with a Falcon4i direct electron detector.  The TF20 200 kV electron microscope has two cryo-sample holders, a high tilt tomography holder and a 4k x 4k CCD camera. Both the Krios and TF20 have SerialEM installed and have been calibrated for collecting tomographic tilt series and automated data collection. The facility also has a 100 kV Morgagni microscope with a 1k x1k AMT CCD camera for screening negative stain samples, two ThermoScientific Vitrobots, one Leica EM GP2, two carbon/metal evaporators, and glow discharge units.

The microscopes are overseen by experienced staff who offer consultation and training in negative-stain and cryo sample preparation, single particle analysis, tomography, data processing and additional computational support.

Mission Statement

The goal of the CSB Cryo-EM Facility is to make TEM accessible to all interested researchers at Vanderbilt. TEM is one of the fastest developing, cutting-edge structural techniques for exploring the organization of biological macromolecules. The unique strength of TEM is its versatility. Structures determined using TEM can span resolution ranges from very low- to atomic-levels (>30–1.8Å) and do not require crystalline samples for analysis.

In pursuit of its goal, the CSB Cryo-EM Facility enables TEM training and outreach by:

  • Providing extensive training to new users.
  • Providing advice and support in specimen preparation, data collection and image processing, computational image analysis, and structure determination.
