Simultaneous analysis of bases, nucleosides and nucleoside mono- and polyphosphates by high-performance liquid chromatography.

A single-column high-performance liquid chromatographic system for the simultaneous separation of bases, nucleosides and nucleoside mono- and polyphosphates has been developed, in which a strong porous anion-exchange resin (Aminex A-14) is used. The chromatographic run, carried out at 55 degrees and at alkaline pH by using a linear gradient both of ionic strength and pH, takes less than 225 min. The quantitative application of the described procedure to the analysis of cell nucleotide pools is reported.
