Ahn, and M.H. Moon, Shotgun Analysis of Phospholipids from Mouse Liver and Brain by Nanoflow Liquid Chromatography/Tandem Mass Spectrometry, J. Chromatogr. B 852:268–277, 2007. Phospholipid (PL) species were determined using nanoflow reversed phase liquid chromatography/electrospray ionization tandem mass spectrometry (LC-ESI-MS-MS). A dual scan method was introduced for the high throughput analysis of complex PL mixtures. Two consecutive LC-ESI-MS-MS runs were made in positive ion mode for phosphatidylcholines (PC) and phosphatidyl-ethanolamines (PE) first followed by analysis in the negative ion mode for phosphatidylserines (PS) and phosphatidylinositols (PI) using the same binary gradient elution with and without formic acid, respectively. The MS analysis of the eluted PL molecules was performed with a precursor scan followed by a data dependent MS-MS scan. Identification was made of 90 and 60 PL species present in mouse liver and mouse brain, respectively.
