Cryo-focused ion beam milling
WebAbstract. Cryo-electron tomography (CET) is ideally suited for bridging the resolution gap between molecular and cellular structural studies. However, CET is limited to a sample … WebLarger cells, and even tissues, can be prepared for CryoET by thinning, either by cryo-sectioning or by focused ion beam (FIB) milling. In cryo-sectioning, frozen blocks of cells or tissue are sectioned into thin samples with a cryo-microtome. In FIB-milling, plunge-frozen samples are exposed to a focused beam of ions, typically gallium, that ...
