Located in I-court (I – 093) of the Health Sciences Building on the University of Washington campus (click here for directions), the Mass Spectrometry Center is an open-access self-sustaining instrument laboratory providing a wide variety of mass spectral services to the University and the research community-at-large (including commercial) on a recharge basis.
The Mass Spectrometry Center offers the following services:
- Instrument Training – Training services available to center users:
- Basic UPLC operation and gradient development
- Compound optimization for quantitative assays
- Basic mass spectrometry analysis on all center platforms
- Software training for quantitative and qualitative analysis software
- Submitted Sample Analysis – Examples of routine analysis include:
- High resolution accurate mass measurements of small molecules
- Lipids, proteins, and small molecules
- Protein digest peptide mapping (discovery proteomics)
- Whole protein mass determination
- LC-MS separations of complex mixtures
- Assay Development – Contracted development of quantitative (MRM) and qualitative assays:
- Complete quantitative assays including compound optimization and separation methods
- Extraction protocol development for quantitative assays including recovery calculations
- Calibration curve development for absolute quantification
- MRM Quantitative Proteomics – We offer support on quantitative proteomics including:
- Development of quantification methods and digests for proteins
- Quantification in tissues, cells, cell lines, biofluids
About the Center
The Center serves as a resource offering analytical and instructional expertise in contemporary mass spectrometric techniques and instrumentation with the primary aim of providing researchers with “hands-on” training and ready access to “state-of-the-art” instrumentation needed to develop and meet their research interests. Examples of routine analysis are: Low and High Resolution mass analysis, metabolomics, Metid, analyte quantitation, and structural elucidation.
