On account of its excellent resolution and high throughput, cryoSEM imaging has recently seen resurgence. In this work, we report on the development of cryogenic triple ion gun milling (CryoTIGM), a broad ion beam milling technique for cryo-planing of vitrified, frozen-hydrated specimens. We find that sections prepared with CryoTIGM are smooth over exceptionally large areas (∼700,000 μm2), and reveal ultrastructural details in similar or better quality than freeze-fractured samples.
