CALL FOR PROPOSALS: neutron beam time at the Protein Crystallography Station at LANL


From: Suzanne Zoe Fisher
Date: 2 May 2012 22:30



Dear Colleague,
The Protein Crystallography Station is a high performance neutron beamline located at the spallation neutron source at the Los Alamos Neutron Science Center in Los Alamos, NM. We are also pleased to announce that our in-house X-ray diffractometer is installed and available for user experiments as well. We also offer full support for perdeuterared protein expression, purification, and crystallization. The PCS routinely collects data on H/D exchanged samples and perdeuteration is not a requirement.


We are accepting proposals for our neutron beam run cycle starting 4th August and running until late December 2012. 

We strongly encourage you to contact the instrument scientists for questions concerning sample preparation, instrument capabilities, sample environments, and/or proposal preparation:
