Welcome!
The Structural Biology Laboratory (SBL) provides access and assistance with the techniques of X-ray crystallography and single particle cryo-electron microscopy reconstruction, and assistance with structure determination, refinement and interpretation. For X-ray this includes assistance with crystal screening and optimization, in-house X-ray diffraction screening and data collection, synchrotron data collection at the Advanced Photon Source (APS) for single crystals and Small Angle X-ray Scattering (SAXS) measurements. For single particle cryo-EM, this includes assistance with protein sample preparation, grid preparation for negative staining and cryo-EM, grid optimization, collection, processing and analysis of data from in-house microscopes, structure determination and validation.
