RIKEN SPring-8 Center Life Science Research Infrastructure Group
Group Director: Nobutaka Shimizu (D.Sc.)
Research Summary
We pioneer and sophisticate advanced techniques in macromolecular crystallography (MX), small-angle X-ray scattering (SAXS), and cryo-electron microscopy (cryo-EM) single-particle analysis, utilizing SPring-8, SACLA, and cryo-EM facilities to propel structural life science and drug discovery research. In parallel, we optimize the methods and environments for producing sample molecules and evaluating their properties and functions. Additionally, we collaborate with experts both within and outside RIKEN to promote integrative structural biology, aiming for a comprehensive understanding of biomolecular interaction mechanisms across broad spatiotemporal scales.
