A HPLC method for determination of 6-thioguanine nucleotide in DNA was developed. Leukocyte DNA was isolated from peripheral blood, derivatized with chloroacetaldehyde and the formed etheno derivatives N(2),3-etheno 6-thioguanine (epsilon6TG), 1,N(6)-etheno adenine (epsilonA) and N(2),3-etheno guanine (epsilonG) were released from the DNA backbone by hydrolysis at pH 6.0 and 80 degrees C for 60 min. After extraction of epsilon6TG by immobilized metal ion affinity chromatography (IMAC) the sample was analysed by ion-pair reversed-phase HPLC with fluorescence detection. The limit of quantification was 9.0 nM and the intra- and interday precision ranged from 2.8 to 15.5%. In a small cohort of eight children with acute lymphoblastic leukaemia (ALL), a median of one 6-thioguanine base was found for each 3000 normal bases (range 1:2000-1:11000).
