PROTEIN CRYSTALLOGRAPHY
Facilities

The protein crystallography facilities at the SRS have been supplemented by the addition of a new rapidly tunable MAD station, 10.1, in 2004. Some brief specifications of the PX stations are given here.

Station Intensity (Relative) Wavelength (Å) Tunability Detector Current Status Notes
7.2 3 1.488 Slow Mar345 IP Development 1
9.5 1-4 0.6 - 2.0 Rapid Mar165 CCD & fluorescence detector Development 2
9.6 10 0.87 Fixed ADSC CCD Operational 3
10.1 20-40 0.8-2.7 Rapid Mar225 CCD & fluorescence detector Operational 4
14.1 10 - 20 0.98 or 1.488 Slow ADSC CCD & fluorescence detector Operational 5
14.2 20 - 40 0.979 Slow ADSC CCD & fluorescence detector Operational 6

 

  1. Not scheduled for users since March 2000 but used for hardware developments.
  2. To be commissioned as a Materials Science station
  3. New software installed in 2004: PXGEN++ and DNA for automatic processing and startegy calculation.
  4. Station operates with a large-area MAR CCD, DTB and automatic sample-changer.
  5. Fluorescence detectors and software for MAD experiments now available.
  6. ACTOR system and software (PXGEN++/DNA) available for motorised mounting and automatic alignment/screening of crystals.

N.B. All stations are equipped with cryo-coolers for data collection at 100K, and have computing facilities for data transfer, backup and analysis. Packages include DENZO, MOSFLM, CCP4 (CCP4i), SOLVE and many others.

A Data Collection Service for users is now available.

Protein crystallography staff will develop other aspects of the facilities at the SRS:

Comments and suggestions for further development are welcome.
