Citing the P30 Cancer Center Support Grant (CCSG)

The mission of the Proteomics Shared Resource (PSR) is to provide the University of Arizona Cancer Center investigators with a dedicated facility and expertise in analyzing proteins for their identity, quantity and function via state-of-the art Modern Mass Spectrometry and peripheral analytical instrumentation.

Over the past funding cycle, the PSR has performed proteomics analyses for Cancer Center members belonging to the four scientific research programs.
