High-performance liquid chromatographic separation of purine deoxyribonucleoside monophosphate-benzo[a]pyrene adducts.
Chromatographic methods that allow the separation of adducts of purine nucleoside 3'-phosphates with the pure enantiomers of the anti-dihydrodiol epoxide of benzo[a]pyrene are developed. The optimization procedure includes evaluation of the effect of buffer molarity, the pH of the buffer, and the role of organic modifiers. The method can be utilized to prepare standards with known absolute configuration that can be further used in the Randerath 32P-postlabeling procedure.
