We have developed a highly sensitive 32P-postlabelling assay for the detection of alkylphosphotriesters in DNA using selective enzymatic DNA hydrolysis, sample preparation by C18 Sep-Pak solid phase extraction and product analysis by HPLC. The assay provides information on the quantity of the alkylphosphotriesters and gives some clues with respect to their identity.
