Microscopy Conference 2023

Visualizing cellulose chains with cryo scanning transmission electron microscopy

LS 1: High-resolution cryo-EM

In 2020, cryo-EM breached another barrierer and it has now been shown that it can visualise individual atoms within a macromolecular complex. Significant improvements in software and mircoscope design were mandatory for this achievement. However, what is possible for ideal samples or test-specimen must not necessarily be true for research-based biological applications, highlighting the prerequisite of sample quality and optimization which continues to be the major challenge en route to atomic-resolution cryo-EM structures. The session will showcase how to improve the sample handling, microscope setup and image processing to obtain high-resolution structures using cryo-EM.
