Citation | Journal: Nat Methods / Year: 2023 Title: Correlative montage parallel array cryo-tomography for in situ structural cell biology. Authors: Jie E Yang / Matthew R Larson / Bryan S Sibert / Joseph Y Kim / Daniel Parrell / Juan C Sanchez / Victoria Pappas / Anil Kumar / Kai Cai / Keith Thompson / Elizabeth R Wright / Abstract: Imaging large fields of view while preserving high-resolution structural information remains a challenge in low-dose cryo-electron tomography. Here we present robust tools for montage parallel array ...Imaging large fields of view while preserving high-resolution structural information remains a challenge in low-dose cryo-electron tomography. Here we present robust tools for montage parallel array cryo-tomography (MPACT) tailored for vitrified specimens. The combination of correlative cryo-fluorescence microscopy, focused-ion-beam milling, substrate micropatterning, and MPACT supports studies that contextually define the three-dimensional architecture of cells. To further extend the flexibility of MPACT, tilt series may be processed in their entirety or as individual tiles suitable for sub-tomogram averaging, enabling efficient data processing and analysis. | |||||||||
