AR filter of the structure of tobacco mosaic virus is now the highest resolution CryoEM structure.

David Bhella, Professor of Structural Virology and director of Scotland’s national centre for CryoEM, shared a remarkable tweet with the world.

They recently trialed the DirectElectron Apollo camera on their JEOL CryoARM 300. After collecting test data on a tobacco mosaic virus (TMV) at several magnifications, they were able to process one dataset to 1.85 angstroms resolution. This 1.85 Å structure of tobacco mosaic virus  is the highest resolution CryoEM structure resolved using helical reconstruction! Interesting fact: the sensor inside is powered by Caeleste!


Caeleste’s Caspar2 sensor makes highest resolution CryoEM image!
