Core Services: Molecular Phenotyping: Directed Metabolomics Lab

As a part of the Michigan Nutrition and Obesity Research center (MNORC), the Directed Metabolomics Core Laboratory provides the University of Michigan research community with the ability to perform quantitative assays for a wide variety of small molecules of biological origin (metabolites). The laboratory works with individual investigators to develop appropriate methods for metabolite analysis. We work with a wide range of sample types, including (but not limited to) cells, tissues, and biological fluids from human subjects, research animals, or other organisms. Typical assays we perform are listed below; however, our capabilities are by no means limited to the compound classes in the list. Please contact us with any inquiries about your analysis of interest.

View example data from selected assays.

Our primary analytical platforms are LC-MS/MS (triple quadrupole), LC-MS (time of flight), GC-MS (electron ionization and chemical ionization), and GC (flame ionization detection).
