The mass spectrometry platform of the CPF is the cancer-focused component of the Biomedical Mass Spectrometry (BioMS) Center, a University of Pittsburgh-wide shared resource located in the Biomedical Science Tower 3 on the Oakland campus. This facility was designed and renovated as a dedicated, state-of-the-art mass spectrometry center, to advance the use and application of mass spectrometry in basic and/or translational research at all levels, from first-time users to experts in the field. The CPF/BioMS Center currently includes twelve modern mass spectrometers that support a wide range of analytical capabilities.
