Abstract

Liquid chromatography-mass spectrometry (LC-MS) is a widely used methodology for measuring lipids at a global level. Combined with an optimal extraction method LC-MS enables the detection and characterization of a wide range of lipid species even of low abundance. Here, we describe two extraction- and LC-MS-based quantitative analytical methods for lipid, acyl-CoA, and acyl-carnitine analyses from either mouse C2C12 myotubes or mouse skeletal tissue. We also describe the use of 13C16-palmitate and its incorporation into acyl-carnitines to show how stable isotope tracers are metabolized within cells and therefore can be implemented for lipidomic flux analysis.
