Large-scale 3D imaging of mouse cochlea using serial block-face scanning electron microscopy
Yan Lu, Fangfang Wang, Haoyu Wang, Philipp Alexander Bastians, Yunfeng Hua
Abstract
This protocol describes how to prepare intact mouse cochleae for serial block-face scanning electron microscopy (SBEM). The detailed workflow includes cochlea fixation, en bloc staining, resin embedding, X-ray microscopy-guided trimming and SBEM data acquisition. This protocol allows large-scale, nanometer-resolution three-dimensional imaging of subcellular structures in a targeted tonotopic range of the cochlea and enables fast volumetric scan at submicron resolution using a compact X-ray microscope. For complete details on the use and execution of this protocol, please refer to Hua et al. (2021).
