Abstract
Despite the recent substantial technological developments in X-ray crystallography, solving and refining structures at low resolutions remain substantial challenges. Many macromolecular crystals, especially those of large molecules or multicomponent assemblies, diffract X-rays to resolutions that are worse than 3.5Å. This report summarizes several recent advances aiding low resolution crystallographic work.
