Cryo-FIB-SEM provides high-resolution information of sub-cellular compartments at their native state
(A) A representative slice from an FIB-SEM acquisition of a plunge frozen mammalian cell. Contrast is most likely generated from differences in surface potential of the different materials. Nuclear pores (black arrowheads) Voxel size: 10 × 10 × 10 nm. Scale bar: 1 μm.
(B–G) Overlays of representative micrographs and organelles segmentation (left) and a slice through the same organelle (right): Golgi apparatus (B), mitochondria (C), multi-vesicular body (D), endoplasmic reticulum (E), lysosome (F), and lipid droplet (G). Scale bar: 0.5 μm.
