WebDec 1, 2024 · Cryo-electron tomography (cryoET) is currently the only technique capable of recording 3D images of biological objects with a resolution in the nanometer range ( Sali et al., 2003). The biological specimen is typically preserved at liquid nitrogen temperatures in a close-to-native state. WebCellular cryo-electron tomography (cryo-ET) is a label-free cryogenic imaging technique that provides 3D datasets of organelles and protein complexes at nanometer resolution. This is done by opening windows into the cell with focused ion beam (FIB) milling of a cryogenically frozen (vitrified) cell.
