Mass Spectrometry Facility
The Mass Spectrometry Shared Resource provides services to elucidate the primary structure of novel proteins and to analyze protein/protein interactions, post-translational modifications and protein levels. The Resource also offers the ability to detect lipids, metabolites, and other small molecules. The equipment in the facility has been upgraded to provide state-of-the-art analysis using microcapillary LC-MS/MS on linear ion traps and Orbitraps.
Facility staff is available to discuss project design and progress. Services include:
- Protein identification using LCMS (in-gel digest, Co-IP, proteomic screens)
- Characterization of post-translational modifications
- Quantitative global proteomic & phosphoproteomic profiling using iTRAQ/TMT, SILAC, or label-free methods
- Quantitative cysteine profiling for global redox proteomics.
- Quantitative (iTRAQ or label-free) profiling of protein complexes for BioID and dTAG screens
- Intact protein mass measurement for drug binding and to support crystallographic studies
- Multiple and parallel reaction monitoring (M/PRM) for peptide, protein, and small molecule quantitation
- Data analysis, merging of separate datasets and statistical treatment of results
- Training in LCMS and MS/MS, both for instrument operation and data analysis
- Consultation in experimental planning and customized experimental design.
We’ve implemented targeted and untargeted LC-MS-based workflows to identify and quantify key primary metabolites and intermediates in a variety of biological matrices (tissues, biofluids, cells, cell culture medium, RNA and DNA). The following classes of compounds are currently covered in our analyses:
- carboxylic acids
- amino acids
- nucleotides and nucleosides
- coenzymes and vitamins
- mono- and disaccharides
- fatty acids
- steroids and hormones
We are able to perform stable isotope (13C, 15N, 2H) tracing analyses, which can be used to measure the activity of specific metabolic pathways, directionality of particular reactions, and potentially reveal their sub-cellular localization.
It is also possible to monitor the uptake and metabolism of drug compounds using customized LC-MS methods.
Please contact Sofia Costa (email@example.com) to discuss any projects or pilot experiments under consideration. It is strongly advised that experimental design and sample collection are agreed upon prior to carrying out the experiments, as these determine the quality of the data we are able to provide. We are happy to discuss collaborating on the application of current methods, or the implementation of novel ones.
Proteomics data is analyzed with the following data analysis packages:
- Mascot and Mascot Distiller
- Proteome Discoverer
Metabolomics data is processed and analyzed using the following software, databases and informatics tools:
- Compound Discoverer
- Human Metabolome Database
