Metabolomics Core

Overview of Services

The metabolomics core provides expertise to quantitate metabolites in biological samples using liquid chromatography/mass spectrometry.  Our mission is to perform the assays and assist in the interpretation of the results.


The targeted metabolomics assays offered are:

  • Acylcarnitines (57 ACs, products of fatty acid and amino acid oxidation)
  • Organic acids (8 OAs, TCA cycle intermediates, products of glucose and amino acid oxidation)
  • Amino acids (30 AAs)
  • Nucleotides (30 nucleotides)
  • Malonyl CoA and acetyl CoA 

Quantitation of these analytes by liquid chromatography/mass spectrometry is achieved by addition of isotopically-labelled internal standards to an array of sample types, including extracts of cells in culture, as well as bodily fluids and tissue extracts of model organisms and human subjects. These modules provide crucial information about metabolic pathways involving the three major classes of nutrients: lipids, carbohydrates, and protein.
