Proteomics and Systems Biology Core

Core Description: Technology is provided to investigators, which permits the characterization and quantification of proteins and metabolites to enable the development of models that predict the dynamic behavior of living systems.

Proteomics: Both nanoflow and microflow liquid chromatography-mass spectrometry (LC-MS) and LC-tandem MS (MS/MS) analyses can be conducted after protease digestion of proteins or complex mixtures of proteins.  Additional services are available for conducting 2D Gel electrophoresis of proteins on large format gels (26 x 20 cm) or small format gels (8 x 10 cm) together with SYPRO Ruby Staining and Scanning, and Cy2,3,5 Dye labeling and Scanning.

Metabolomics: High-resolution nanoflow LC-MS analyses are conducted on samples from control and experimental studies.

Biomarker: Rigorous quantification of serum, plasma, or urinary biomarkers identified by metabolomics studies can be conducted using stable isotope dilution LC-SRM/MS methodology.  The Core services are normally utilized for biomarker validation studies, for disease diagnosis, for detecting the adverse effects of environmental chemicals, or for monitoring the effect of therapeutic agents.
