Synchrotron Serial Crystallography Available at the GM/CA @ APS
Synchrotron serial crystallography experiments are now available to interested users at GM/[email protected]
Samples can be delivered to the x-ray beam via either:
- A Lipidic Cubic Phase (LCP) injector
- A variety of fixed target systems
GM/[email protected] staff have collaborated with user groups to prove the
feasibility at beamlines 23IDB and 23IDD. Structures have been
determined with an LCP injector from Arizona State University (ASU), as
well as with several different types of fixed targets at room temperature
and at cryogenic temperature. Background information and publications
are listed below. For those interesting in using the LCP injector,
please contact Dr. David Kissick ([email protected]); for those
interested in employing fixed targets, please contact
Dr. Craig M. Ogata.
