The Proteomics and Metabolomics Facility provides state-of-the-art mass spectrometry analysis of proteins and metabolites for both basic and clinical cancer research. We strive to serve all internal and external investigators by providing access to mass-spectrometry based proteomics and metabolomics technologies and services.
What is Proteomics?
- Proteomics is the study of proteomes or the systematic analysis of proteins.
- As defined by Merriam-Webster dictionary: "a branch of biotechnology concerned with applying the techniques of molecular biology, biochemistry and genetics to analyze the structure, function and interactions of the proteins produced by the genes of a particular cell, tissue or organism, with organizing the information in databases, and with applications of the data (as in medicine or biology)".
- Proteomics includes not only quantitative and qualitative analysis of all expressed proteins, but also traditional protein structural studies such as protein identification, post-translational modification, protein-protein interactions, and other functional interests related with protein structure.
- Common sample types include gels, solutions, immunoprecipitates, and other protein-containing materials.
What is Metabolomics?
- Metabolomics is the study of small molecules (defined generally by molecular weight less than 1500 Daltons) in biological samples, including both relative and absolute quantitation.
- “Targeted metabolomics” refers to the analysis of a defined subset of molecules, whereas “non-targeted metabolomics” refers to the analysis of all detectable small molecules.
- In addition to measuring total metabolite levels, a second workflow involves isotope tracer analysis (in either targeted or non-targeted mode), in which stable isotope-labeled metabolites can be used to track the flow of atoms in metabolism.
- The most common biological matrices in which we measure metabolites are: cells, media, plasma, whole blood, red blood cells, urine, and tissues. But even more complex matrices (e.g., bone) can be analyzed.
