Mass Spectrometry and Proteomics Facility

Location: 250 Biomedical Research Tower


Contact Person: Dr. Arpad Somogyi


The mandate of the Mass Spectrometry and Proteomics Facility is to provide state-of-the-art instrumentation in all areas of mass spectrometry and proteomics for the surrounding research community. The nature of our laboratory allows for both routine analyses for faculty who cannot afford nor desire the purchase of their own mass spectrometry instrumentation and provides collaborative research requiring advanced experiments by working closely between faculty, students and staff. The MS&P Facility at OSU maintains a well-equipped and well supported laboratory for mass spectrometric analysis. The services offered include accurate mass analyses of small organic molecules, LC-MS of small molecules, polymer analysis, analysis of synthetic peptides and oligonucleotides. We also have considerable experience in the field of proteomics including protein identification, protein purification post-translational modification analysis, iTRAQ, and differential gel electrophoresis (DIGE).
