Single particle cryo-EM uses the particles extracted from thousands of images to reconstruct 3D structures of macromolecules. The yield of an acquisition session at the microscope depends on the time to set up the run and the speed of the acquisition itself. Thermo Fisher Scientific EPU 2 software is designed to maximize SPA throughput. Its simplified user interface and advanced automation ensure that setting up a data acquisition session is faster and more accessible, allowing users to focus on their research and make efficient use of the microscope.
EPU 2 tightly integrates with EPU Data Management and the optional EPU Quality Monitor. The Thermo Fisher Scientific Athena software platform and the server hardware used by the Falcon 4 and the Selectris Imaging Filter form the basis for this data management solution. It allows users to organize, view, and share single particle analysis projects easily. EPU Quality Monitor analyzes and visualizes EPU 2 data on-the-fly, enabling users to judge image quality of running or completed acquisitions remotely. The combination of EPU 2, EPU Quality Monitor and Data Management helps to generate high-quality results quickly and with confidence.
Designed for stability and speed, the Thermo Scientific Selectris and Selectris X Imaging Filters are post-column imaging filters that improve the contrast of TEM images, resulting in high-resolution structures up to atomic resolution. Paired with the latest generation Thermo Scientific Falcon 4 Direct Electron Detector, Selectris Filters enable you to obtain high-resolution structures quickly, revealing new biological insights. To further increase the productivity and ease-of-use of your cryo-electron microscopy (cryo-EM) research, these filters are fully integrated into Thermo Scientific EPU Software, Thermo Scientific Tomography Software, and instrument operation software. The Selectris and Selectris X Imaging Filters are available on Thermo Scientific Krios and Glacios Cryo-TEMs.
