The molecular species of sphingoid bases were tagged with the fluorescent amino group reagent, 4-fluoro-7-nitrobenzofurazan (NBD-F). The NBD-sphingoid bases were analyzed by a highly selective and sensitive liquid chromatography–electrospray ionization tandem mass spectrometry (LC–ESI–MS/MS) technique capable of reliable detection of several fmol of the(More)
