Single Crystal X-ray Diffraction

    Three-dimensional atomic structures of small molecules may be unambiguously determined by employing the technique of single crystal X-ray diffraction. Such chemical compounds, which may be of either chemical or biological interest, include—but are not limited to—new synthetic chemicals, catalysts, pharmaceuticals, and natural products.

    Once a crystal of the compound under investigation has been grown, the complete diffraction pattern—which may consist of thousands of individual measurements—resulting from the interaction of an intense X-ray beam with the crystal is collected on an area detector that can collect a vast number of observations in a single exposure. Automated structure solution is accomplished by analysis of the complex diffraction pattern. This same technique can also be used to produce detailed electron density maps of molecular bonds.

    Protein crystallography is a powerful structural biology technique that provides atomic resolution details about proteins and other macromolecular molecules involved in all aspects of life and disease. Rigaku is a world leader in providing instrumentation that can improve productivity at many levels, from making crystallization solutions to automatically mounting crystals and collecting high-resolution X-ray diffraction data sets.

      Dr. Samantha N. MacMillan
      X-ray Diffraction Facility at Cornell University
    • There has been good help and advice from personnel from Rigaku Oxford Diffraction and I would definitely recommend this instrument to anyone considering making a purchase of a new diffractometer.

    • I would recommend the XtaLAB Synergy-S system for structural biology labs because it is very useful for checking the diffraction quality of protein crystals and allow to collect high-quality data for “non-problematic”, well-diffracting protein crystals.

    • This new machine with a rotating anode generator has been a game changer for our institute. Data from good-diffracting crystals can be collected within minutes!

    • The machine is much faster, enabling crystals to be quickly screened to ensure only the best crystals are measured. lt permits small, less perfect crystals to be screened, as well as providing publishable results in a matter of minutes to hours for favourable specimens.

    • The single most important benefit that the instrument brings to the lab is the ability examine very small crystals in a short timeframe, whether that size constraint is forced upon you by the crystal availability, or whether you enforce it in order to isolate a single high-quality fragment from a larger (perhaps multiple) crystal.

      Prof. Kenneth Shankland
      Chemical Analysis Facility, University of Reading
    • We get significantly better data with the new instrument. The speed at which we can collect data and solve a structure is impressive. Now, we use fast data collections (minutes long) to work out the connectivity of the compound.

    • The Synergy-R is a fantastic machine and we would unconditionally recommend scheduling a demo, if your institution would like to amplify their lab's capabilities with a high-end diffractometer.

    • It is very common for these students to have some initial trepidation and anxiety about using valuable, high powered research equipment, but the approachability of the XtaLAB mini massively reduces this issue.

    • What might have started out as one of the usual diffractometer control programs, has evolved into an indispensable tool, which has the ability to obtain very good data, or better, from some of the most challenging samples.
