title: Separation of choline- and ethanolamine-labeled metabolites by ion-exchange high-pressure liquid chromatography.
abstract: Two methods utilizing ion-exchange high-performance liquid chromatography have been developed for the separation of choline- and ethanolamine-containing metabolic precursors for phosphatidylcholine and phosphatidylethanolamine. Both methods employ an analytical anion-exchange column supplemented with a cation-exchange column; the latter is required only to separate betaine from choline. Complete separation of choline- and ethanolamine-labeled metabolites from extracts of Chinese hamster ovary cells can be achieved in 20 min.
