Abstrakt:	Serial Block Face Scanning Electron Microscopy (SBF-SEM) is one of several volume electron microscopy (vEM) techniques whose purpose is to reveal the nanostructure of cells and tissues in three dimensions. As one of the earliest, and possibly most widely adopted of the disruptive vEM techniques there have been hundreds of publications using the method, although very few comparative studies of specimen preparation parameters. While some studies have focused on staining and specimen acquisition no comparison of resin embedding has yet been conducted. To this end we have surveyed the SBF-SEM literature to determine which resins are commonly used and compared them in both cellular and fixed tissue samples in an attempt to optimize sample preparation for: effectiveness of resin infiltration, resistance to charging and beam damage and clarity of image in the resulting data set. Here we present the results and discuss the various factors that go into optimizing specimen preparation for SBF-SEM. (Copyright © 2023 Elsevier Inc. All rights reserved.)
