Mission, Goals, Capabilities
The X-ray Crystallography & Molecular Characterization Facility is a Kimmel Cancer Center (KCC) Core Resource that provides multiple Jefferson research groups with access to state-of-the-art instrumentation.
All stages of structure determination by X-ray crystallography methods are supported, including crystallization screening, X-ray diffraction analysis, and computational processing of diffraction data. The Molecular Characterization equipment includes a Biacore 3000 surface plasmon resonance (SPR) biosensor, an analytical ultracentrifuge, a circular dichroism spectrophotometer, two isothermal titration calorimeters, and a KinExA 3000 flow fluorimeter. Thus, the Facility maintains multiple types of advanced instrumentation that are critical to the progress of several research programs at Jefferson that span multiple TJU Departments. The Facility strives to maintain this equipment in top condition with minimal downtime for the Jefferson community.
