Proteomics Core Facility
Sunnybrook Research Institute
Toronto, Ontario, Canada


The proteomics core facility at Sunnybrook Research Institute (SRI) provides kinetics analysis by surface plasmon resonance, peptide/protein fractionation and purification, and mass spectrometry-based protein identification and characterization.

We provide services and methods development for these research projects:

  • Label-free differential proteomics: Proteins are fractionated (reversed phase chromatography , 2D gel, 1D gel (GeLC) or IEF), digested and identified by LC-MS/MS. Quantitative information is provided through Agilent Spectrum Mill software. View the reference.

  • Differential proteomics with stable isotope labeling: Typically, two protein populations are labeled (for example, by iTraq, ICPL, SILAC) and mixed. The mixed proteins are fractionated, digested and identified by LC-MS/MS.

  • Protein identification and characterization: Protein identification/characterization from silver or coomassie stain gel or from solution.

  • Phospho-peptide enrichment and analysis by electron transfer dissociation MS (ETD-MS).

  • Measurement of interaction kinetics by Biacore 3000.

  • Sample fractionation by HPLC such as:
    • size exclusion (gel filtration);
    • reversed phase; and
    • strong cation exchange chromatography.

  • Experiment design, data interpretation and technical support in sample preparation are available.
