Ask the Experts: March 22, 2023 | Leveraging the integration of cryo-EM and X-ray based methods for a comprehensive approach to structural biology


Researchers depositing structures in the Protein Database are increasingly using multiple characterization methods for protein structure determination. By doing so, they can solve more challenging structures with greater information, especially when a single method cannot fully complete a structural determination. For example, while X-ray crystallography cannot always characterize samples that are difficult to crystalize, cryo-electron microscopy using microcrystal electron diffraction can solve proteins that only form microcrystals with even the best preparation.

Service centers offer both the instrumentation and the expertise to help researchers examine their samples using multiple methods. They make it possible for academic and pharmaceutical researchers to explore what’s possible when they need analysis above and beyond individual collection.

In this webinar, we'll discuss research on submicron crystal detection and handling as well as the collaboration between the National Crystallization Center and the Cryo-EM Center at the Hauptman-Woodward Medical Research Institute, where the teams are working to further develop microcrystal methods.
