Macromolecular Crystallography (MX)

The Diamond MX village currently comprises five state-of-the-art undulator beamlines - three high brilliance MAD beamlines (I02, I03, I04), a fixed wavelength beamline (I04-1) and a microfocus MAD beamline (I24). We offer a wide range of facilities and capabilities including microbeams, in situ (in-plate) screening and data collection, sample humidity control, UV-Vis spectroscopy and data collection from pathogenic samples.
- fast sample changers accepting SPINE standard pins in Unipucks
- fully automated data analysis (Xia2, DIMPLE, FastDP, FastEP, MrBUMP)
- state-of-the-art Pilatus Pixel Array Detectors
Specialised high flux microfocus beams for microcrystal data collection or the illumination of subvolumes of larger inhomogeneous crystals.
In situ data collection and sample characterization directly from crystals in their crystallization plates.
Control of the sample crystal's relative humidity with the aim of improving diffraction quality through improved packing of protein molecules constituting the lattice.
On-line and off-line UV-Vis spectroscopy of macromolecular samples to study enzyme reaction mechanisms and radiation damage.
Crystal reorientation to optimize data collection strategies for anomalous diffraction data collection and low symmetry spacegroups, or very long axis unit cells.

I24 has a new floor in the experiment hutch and beyond.
The crystal washer is ready for use in I02.
I04-1 will be operating with fast gripper in run 5 - expect sample changes in around 37 seconds.
