Identification and quantification of proteins and other biomolecules using advanced mass spectrometry methods and discovery of novel drug candidates through integrated bioanalytical services.
The Proteomics and Molecular Analysis Platform specializes in identifying and quantifying proteins using advanced mass spectrometry techniques to detect changes in health and disease for biomedical and clinical applications. Platform staff have extensive experience in quantitative proteomics, advanced bioinformatics, mapping proteomics data onto biological pathways and protein functional interaction analysis. The Proteomics and Molecular Analysis Platform supports discoveries of new drug molecules and provides top-flight bioanalytical support to the scientific and biotechnology communities. The platform is noted for multidisciplinary expertise in areas such as analytical chemistry, nuclear magnetic resonance (NMR) spectroscopy, liquid chromatography-mass spectrometry (LC-MS), and X-ray crystallography. The platform’s expertise allows handling of a wide range of investigator-initiated research challenges, and this translates into using the platform’s diversified set of instruments for multiple applications: new drug candidate fragment-based screening (NMR), protein target characterization (proteomics), drug and target structures (X-ray), LC-MS support for chemistry, LC-MS/MS for off target effects, LC-MS/MS-MRM assays for drugs from cells, plasma and tissue.
Protein identification, including proteins from tissues, biological fluids and gels; protein characterization, including assessment of protein mutations, variations and deletions; post-transitional modifications, including detection and quantification of post-translational modifications including phosphorylation, acetylation, methylation, ubiquitylation; protein quantification, including Multiple Reaction Monitoring (MRM), and Data Independent Acquisition (DIA) and high-resolution quantification methods; and consultation, sample preparation, data interpretation and bioinformatics analysis. Targeted small molecule analysis, bioanalytical and biophysical services including fragment-based screening (NMR) and analysis of X-ray crystal structures.
