The SGX Collaborative Access Team (SGX-CAT) offers "Express Crystallography", a MAIL-IN protein crystallography service.  Under this program, researchers with qualified non-proprietary experiments can obtain data from the X-ray facilities at SGX-CAT.  SGX personnel will screen and collect data from crystals based on specifications from the program's participants.

A complete description of the Express Crystallography service and its procedures is contained in the pdf file available here (download link).

Access to Express Crystallography is through the General User Program of the Advanced Photon Source at Argonne National Laboratory.  Additional information on the features and requirements of the General User Program is available from the APS website.
