X-ray Crystallography at Oklahoma State University (OSU)
A great resource is available to researchers at OSU through the Single-Crystal X-ray Diffraction Facility located in the Department of Chemistry. This facility is equipped with two single-crystal X-ray diffraction units from Bruker AXS. Both instruments in the facility are equipped with computers to store data files and are loaded with programs for data reduction and data preparation. The units are also equipped with DVD/CD read/write drives for data archiving.
The SMART APEX II instrument is a small-molecule (usually less than 1000 atoms) machine with a molybdenum source and a D8 3-axis goniometer. A KRYO-FLEX low temperature device is available with the instrument for data collection at low temperatures. This instrument is great for examining drug compounds.
The MICROSTAR/X8 PROTEUM system is specifically designed for protein crystallography. It is equipped with a copper rotating anode, Montel multilayer optics to assure monochromatic X-rays, and a Kappa 4-axis goniometer to maximize data collection options. An Oxford Cryostream COBRA low temperature self-generating nitrogen device is attached to allow for data collection on cryo-preserved protein crystals.
The X-ray Facility director, Dr. Stacy Benson, is available for consultations regarding these instruments' capabilities and uses, protein purification requirements, crystallization techniques, data collection strategy, structure refinement, and other concerns dealing with X-ray crystallography. Furthermore, he is eager to help answer questions on protein structures.
