Thompson1, Juan Sanchez-Weatherby1, Michael A Hough1,2 1Diamond Light Source Ltd, Harwell Science and Innovation Campus, 2Research Complex at Harwell, Harwell Science and Innovation Campus We present a protocol for the crystallization of proteins using the crystallization facility in the Research Complex at Harwell and subsequent in situ X-ray crystallographic data collection from crystals within the plates at Diamond's Versatile Macromolecular Crystallography in situ (VMXi) beamline. We describe sample requirements, crystallization protocols, and data collection guidelines.
