MX in a nutshell
Macromolecular crystallography (MX) is a technique used to determine the three-dimensional structure of biological macromolecules, such as proteins, DNA, or RNA, through X-ray diffraction methods.
The MX Facilities at PSI
The Macromolecular Crystallography group is responsible for three beamlines at the Swiss Light Source, the Cristallina-MX endstation at SwissFEL, and the Crystallisation Facility.

PILATUS4 detector arrives at PXIII
On April 4, 2025, a Dectris Pilatus4 2M detector was successfully installed at beamline PXIII. In the coming weeks, this new detector will be used to measure the first macromolecular crystallography (MX) experiments using the SLS 2.0 machine.
