Separation of six DNA bases by ion pair--reversed phase high pressure liquid chromatography.
An ion pair-reversed phase chromatography system is described which separates six of the bases normally found in prokaryotic and/or eukaryotic DNA from each other and from uracil, the characteristic base found in RNA. The effect of varying pH and the percentage of methanol in the column buffer is described. The addition of the ion-pairing reagent heptane sulfonate was shown to be necessary to achieve separation of all of these bases.
