title: Detection and separation of intracellular 1-beta-D-arabinofuranosylcytosine-5-triphosphate by ion-pair high-performance liquid chromatography.
abstract: An ion-pair high-performance liquid chromatographic method, using a reversed-phase C18 column, was developed to provide an isocratic, sensitive, fast and reproducible separation of intracellular 1-beta-D-arabinofuranosylcytosine-5-triphosphate and its measurement at a low limit of 5 pmol by ultraviolet absorbance at 280 nm with a coefficient of variation lower than 10%. A rapid separation is achieved by using a backflush procedure at 16 min and the retention time is 14 min.
