Establishing and performing targeted multi-residue analysis for lipid mediators and fatty acids in small clinical plasma samples

Abstract

LC-MS/MS- and GC-MS-based targeted metabolomics is typically conducted by analyzing and quantifying a cascade of metabolites with methods specifically developed for the metabolite class. Here we describe an approach for the development of multi-residue analytical profiles, calibration standards, and internal standard solutions in support of a fast, simple, and low-cost plasma sample preparation that captures and quantitates a range of metabolite cascades.
