Background:

  • High-throughput data collection is crucial for macromolecular crystallography.
  • Automated sample handling is needed for efficient integration into synchrotron beamlines.
  • Current methods can limit the speed of crystal screening and data acquisition.

Purpose of the Study:

  • To develop and test an automated sample mounting and alignment system for macromolecular crystallography.
  • To improve the efficiency and reliability of data collection at synchrotron facilities.
  • To create a system capable of handling a large number of cryo-protected samples.

Main Methods:

  • Development of a robotic sample-mounting subsystem with random access to 112 samples stored under liquid nitrogen.
