WebSerial-section SEM is a technique in which serial ultrathin sections are mounted on a rigid substrate, and images of these sections are obtained by SEM (Fig. 1). Here, we describe the various steps of serial-section SEM for the Golgi apparatus. 8),9) Trimming of resin First, a resin block is trimmed into a trapezoidal shape using a razor blade. WebEMSerialblockFIG 1. One oddity of the SEM method is that the block-face image collected via either secondary electrons or backscattered electrons is derived from a depth of view into the block face that is variable. Potentially one could view deeper than a typical thin section (ranging from 20–200 nm) depending mostly on the accelerating voltage.
WebJun 30, 2024 · Serial block face SEM imaging is a powerful tool to obtain high resolution 3D datasets of different sample types and tissues at nanometer resolution.
