Advances in atomic resolution cryo electron microscopy.
Atomic-resolution cryo-EM is finally here. Structural biologists used a Thermo Scientific Krios G4 Cryo-TEM equipped with a Thermo Scientific Selectris X Imaging Filter to achieve record-breaking resolution results, recently featured on the cover of Nature and other recent articles from Science and Nature . Researchers from the Medical Research Council Laboratory of Molecular Biology in Cambridge, UK, obtained a 1.2 ångström resolution structure of the iron-storing protein apoferritin. They also achieved a 1.7 ångström resolution of membrane protein (GABA receptor), with an even sharper resolution in key parts of the protein. This human membrane protein has target sites for general anesthetics, benzodiazepines, barbiturates and neuroactive steroids, making it very relevant to structure-based drug discovery. In addition to the resolution leap, the Selectris technology will also significantly impact productivity. By having a better filter and camera, scientists will be able to achieve a specific resolution with much less data.

Cryo-EM: What’s Next
August 13, 2020
Discover what you can do with atomic-resolution cryo-EM through the Selectris Imaging Filters and latest Falcon 4 camera. See the record-breaking structure results for single particle and cellular cryo-tomography from MRC-LMB, MPI Biochemistry, IST Austria, and others. Learn the potential applications of the Selectris for small proteins (<100kDa) because of improved imaging contrast through zero-loss filtering. High resolution also helped achieve better model building leading to corrected chemistries.
