Mass Spectrometry Center

 
Book Lab

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:

  1. 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
  2. Submitted Sample Analysis – Examples of routine analysis include:
    • High resolution accurate mass measurements of small molecules
    • Lipids, proteins, and small molecules
    • MALDI-TOF
    • Protein digest peptide mapping (discovery proteomics)
    • Whole protein mass determination
    • LC-MS separations of complex mixtures
    • GC-MS
  3. 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
  4. 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.
