Welcome to the Campus-Wide UCSD Proteomics Facility

Biomolecular and Proteomics Mass Spectrometry Facility

The overall goals of the Biomolecular/Proteomics Mass Spectrometry Facility are to collaborate with University of California San Diego (UCSD) researchers and to collect the highest quality mass spectrometry data possible on biological samples. The facility is actively engaged in developing proteomic technologies and also provides access to more routine instrumentation for protein and peptide mass spec analyses.
