The concentrations of 2'-deoxyribonucleoside-3'-monophosphates remaining in calf-thymus DNA digests after nuclease P1 digestion or extraction into 1-butanol, the most commonly used adduct enrichment procedures prior to the application of the 32P-postlabelling assay, were measured using HPLC and 32P-postlabelling methods. When 10 micrograms of DNA digested to mononucleotides was used, the total amount of nucleotides remaining in the samples were approximately 4 and approximately 14 pmol after nuclease P1 treatment or 1-butanol extraction respectively. The influence of various concentrations of normal nucleotides on the labelling efficiency of a 2'-deoxyguanosine-3'-monophosphate adduct of benzo[a]pyrene diol-epoxide was also studied and found to depend upon the ratio of normal nucleotides/adducted nucleotides present in the sample. Also, the ATP/normal nucleotides ratio in the phosphorylation reaction may affect the quantitation of the adducts and thus deserves due consideration.
