Proteomics Shared Resource Services

We provide a diverse range of services to characterize peptides, proteins, and proteomes from a variety of samples (including immunoprecipitates, whole cell lysates, tissues, biofluids, etc), including but not limited to the following1,2:

  • Molecular weight determination of protein/peptide
  • Protein identification from gel bands
  • Protein identification from complex mixtures
  • Characterization of post-translational modifications (PTMs): phosphorylation, acetylation, O-GlcNAcylation, etc.
  • Protein quantification: Isobaric tagging for relative and absolute quantitation (iTRAQ), Difference gel electrophoresis (DIGE), and label-free quantification (including SWATH)
  • Targeted quantification by Multiple Reaction Monitoring (MRM) and Parallel Reaction Monitoring (PRM)
  • Others: 1-D gel electrophoresis, 2-D gel electrophoresis, MesoScale ECL ELISA

‚ÄčWe are glad to help develop methods according to your specific needs.

All investigators (especially first-time users) are encouraged to contact Dr. Junfeng Ma ( and/or Dr. Stephen Byers ( for consultancy regarding experimental design, sample prep, as well as cost estimate.
