WebCryoelectron microscopy (cryo-EM) is an increasingly popular method to elucidate the structures of macromolecular complexes. However, in many applications the resolution of cryo-EM densities is limited to the low or intermediate resolution regime, that is, (10 Å) − 1 or worse. Therefore, unambiguous molecular interpretation of cryo-EM ... WebJan 19, 2024 · The standard practice for crystallographic characterization involves diffraction-based methods, which rely on electron or X-ray microscopy techniques.
