Liquid chromatography tandem mass spectrometry (LC-MS/MS) is a sensitive and robust approach for the identification and quantitation of lipid mediators including the specialized pro-resolving mediators (resolvins, maresins, protectins and lipoxins), and the classic eicosanoids. Due to the relatively low concentration of these molecules in biological samples, this methodology is classically coupled with solid phase extraction (SPE) techniques that enhance the sensitivity of the assay. Herein, we provide a step-by-step description of instrumentation employed in the both SPE and LC-MS/MS and detailed methodologies employed in the extraction of these lipid mediators and their identification and quantitation using LC-MS/MS.
