About the use of cryo-electron microscopy

KEK Cryo-EM Facility operates two cryo-electron microscopes, a 300 kV Titan Krios G4 and a 200 kV Talos Arctica G2 (Falcon 4), both manufactured by Thermo Fisher Scientific. The facility has three primary missions:
　1. Providing machine time to academic and industrial users for more than 200 days a year
　2. Assisting with grid freezing, data collection, and, if necessary, single-particle analysis
　3. Supporting the adoption of cryo-EM techniques

Academic users can access KEK cryo-EM through BINDS.
□ Applications for KEK cryo-EM BINDS projects are always welcome. Please apply here.
