High-Throughput Analysis of Sphingosine 1-Phosphate, Sphinganine 1-Phosphate, and Lysophosphatidic Acid in Plasma Samples by Liquid Chromatography–Tandem Mass Spectrometry

Abstract

Our validated LC-MS/MS methodology for quantifying LPA, S1P, and SA1P features simple sample preparation and short analysis times, therefore providing a valuable tool for diagnostic evaluation of these lysophospholipids as biomarkers.
