Application and characteristics:
This instrument is used for determining the crystal structure of biological macromolecules (such as proteins, nucleic acids) and small molecules, as well as for single crystal structure analysis. It plays a crucial role in studying the structure-function relationship of biomacromolecules and small molecule drugs. The instrument includes a liquid nitrogen cooling system for low-temperature data collection, allowing the measurement of crystals that are unstable at room temperature and improving diffraction data quality. Additionally, the instrument is equipped with a microscope for crystal observation, handling, and cryoprotectant treatments, and it features a high-performance computer workstation for 3D structure analysis and refinement.
