The Southeast Regional Collaborative Access Team (SER-CAT) is an organization consisting of 22 Member and 5 Associate institutions, formed in 1997 to provide third generation x-ray capabilities to macromolecular crystallographers and structural biologists in the southeastern region of the U.S. 

Emphasis is placed on de novo SAD/MAD structure determination, high-resolution structural analyses, large unit cells, drug design, structural genomics, soft X-ray data collection and next-generation beamline automation. SER-CAT is located at the Advanced Photon Source, Argonne National Laboratory, and is operated by the University of Georgia, with  Professor Bi-Cheng Wang as Director.

Please peruse the pages of our website to find out more about SER-CAT and how we are "shining a new light" on protein crystallography.  Have a look at The SER-CAT Spectrum, our newsletter, to learn about recent breakthroughs.  As always, your comments and suggestions are welcome. 

Thank you for visiting!

April 17, Scripps - Florida  (enlarged photo)

The 14th Annual SER-CAT Symposium was held on April 7, 2017 on the Scripps Research Institute – Florida Campus. The meeting featured talks related to the APS upgrade, highlights of scientific advances enabled by SER-CAT data, new user tools available at SER-CAT and the presentation SER-CAT Young Investigator and Outstanding Awards. A posted session followed.

Dr. Stephen Streiffer, the ANL Associate Laboratory Director for Photon Sciences presented current plans for upcoming APS upgrade followed a discussion with the meeting participants on the upgrade will impact SER-CAT capabilities and support new science.

Meeting participants discussed outstanding research projects conducted at SER-CAT throughout the year. SER-CAT beamline scientists shared the beamline advances including new sector specific hardware and software, and data collection features. SER-CAT director Dr. Bi-Cheng Wang presented the “SER-CAT Pilot Project: Phase II – Extending the concept of color photography to routine chromatic X-ray Crystallography”.

SER-CAT sincerely thanks the Symposium's organizing committee Dr. Tina Izard, Ms. Candace Morrow and the staff at the Scripps Research Institute – Florida Campus for planning and organizing this year's informative and very enjoyable event. Our sincere thanks to all speakers and participants for making this year's symposium such a successful event.

CONGRATULATIONS SER-CAT's 2017 Award Winners!!


The 2017 SER-CAT Outstanding Science Award was presented to Dr. Jochen Zimmer (boxed), University of Virginia for his work on “Observing cellulose biosynthesis and membrane translocation in crystallo”. Since Dr. Zimmer could not attend the Symposium, the Award was received from Dr. B.C. Wang by Dr. Owen Pornillos, the SER-CAT Board member form Virginia.


The 2017 SER-CAT Young Investigator Award was presented to Mr. William Bradley O’Dell, North Carolina State University, by Dr. B.C. Wang for his researchon “Oxygen activation by a lytic polysaccharide monooxygenase”.

Special thanks also to all of the nominators for this year's event.

* * * SER-CAT's 20th Anniversary * * *

This year SER-CAT is celebtating its 20th year of operation. We have put together a slide show (below) highlighting SER-CAT's early history which B.C. Wang presented at the Scripps-Flordia SER-CAT Symposium.

* * * SER-CAT Staffing Changes * * *

SER-CAT bids a fond farewell to Kathy Savage and Gina Ranieri. Since 2000 Kathy has served as the SER-CAT Administrative Coordinator where she played an important role in the establishment, and success of SER-CAT today. She is retiring after 30 years' service to UGA. SER-CAT wishes Kathy a healthy and happy retirement. Gina our User Support Coordinator has left us to pursue a career at Procter & Gamble. SER-CAT wishes Gina all success in her new career.

SER-CAT welcomes Michael Molitsky,
Zhi-Qui (Lily) Li and Jackie Taylor. Mike as SER-CAT Senior Beamline Engineer will assume John Gonczy’s duties related to beamline matters.  John was one of the original members of the SER-CAT construction team. We wish John the best in his retirement. Mike was the Principal Beamline Scientist at SBC-CAT from 2004 to 2016 and was responsible for optic and hardware improvements.

Lily and Jackie will be joining the SER-CAT Administrative Office at UGA. Lily has been with us since 1996 and has been promoted to SER-CAT Program Coordinator where she will assume the most of Kathy Savage's outreach and administrative duties while Jackie will serve as the SER-CAT Administrative Specialist assuming Kathy's accounting duties.

* * * The Eiger 16M Detector * * *

SER-CAT has received delivery of a new Dectris Eiger 16M detector which will be installed on beamline 22ID in January. The Eiger is a hybrid photon counter that has a pixel size comparable to that of the Rayonix MX300HS but can collect data up to ten times faster (100 Hz). In addition, unlike the MX300HS, the Eiger has a very high dynamic range reducing saturation problems. When coupled with the new KB mirrors being installed on 22ID the beamline should be ideal for microcrystallography. The Rayonix MX300HS detector will be moved to beamline 22BM significantly increasing data rate and data quality. 

* * * MX300HS Users Guide * * *

A data collection guide for the MX300HS has been prepared and can downloaded by clicking the link below.

MX300HS Users Guide

Please look it over since there are several changes in what you will need to do to collect data and process data with the new detector.

* * * HKL2000 for the MX300HS * * *

A new version of HKL2000 that can process the data from the MX300HS detector is available for download from HKL Research.  Please contact them for download instructions.  You will alos need to get an updated cr_info file.

* * * Data Archiving * * *

Users should avoid bringing firewire drives with metal cases for use at the beamlines.

The metal, being a wonderful heat conductor, is causing thermal failure because of the long download time required for data collection.

* * * SER-CAT Automounters * * *

Both BM and ID Robots are fully commissioned. All first time robotics users must contact Gina Ranieri (SER-CAT's User Support Coordinator) prior to their visit.

The ALS Style magnetic caps are available from Hampton Research, P/N HR4-779

The 18mm Mounted litholoops are available from Molecular Dimensions.

The dry shipping dewars compatible with SER-CAT puck holder are from Taylor-Wharton (Model: CX100 or CXR100). The product vendor is:

SER-CAT's robotic pucks, puck holder and tools are available from the University of Georgia Instrument Shop, 955 East Whitehall Rd., Athens, GA 30602. Please Contact Mr. Lewis Fortner via e-mail ( or  Fax (706-542-7921) for pricing and availability.


* * * Director's Highlights * * *
