University of Colorado Cancer Center, A National Cancer Institute-designated Comprehensive Cancer Center

Structural Biology Shared Resource

The Structural Biology Shared Resource (SBSR) provides University of Colorado Cancer Center members access to instrumentation and expertise in the use of X-ray Crystallography and Nuclear Magnetic Resonance Spectroscopy (NMR). It is one of only two NCI-designated cancer centers with X-ray Crystallography, NMR, high field NMR and synchrotron. 

The SBSR promotes the application of structural studies to the molecular basis of cellular processes that regulate the development and progression of cancer and application of that information to aid in drug design, complementing the strengths of the existing research programs in cell signaling, pharmacology, and cancer.
