In situ studies of membrane biology by cryo-electron tomography

Authors Keller J, Fernández-Busnadiego R Journal Current Opinion in Cell Biology Citation Curr Opin Cell Biol. 2024 Apr 26;88:102363. Abstract Cryo-electron tomography (cryo-ET) allows high resolution 3D imaging of biological samples in near-native environments. Thus, cryo-ET has become the method of choice to analyze the unperturbed organization of cellular membranes.
