since molecules of this type ( d-nps ) are the sole apurinic site containing products resulting from the combined digestion of lightly depurinated dna by snake venom phosphodiesterase and calf alkaline phosphatase [ weinfeld , m. , liuzzi , m. , & paterson , m. c. ( 1989 ) nucleic acids res . 17 , 3735-3745 ] , we were able to devise a postlabeling assay for these biologically important dna lesions .
