title = "(32)P-postlabeling analysis of DNA adducts",
abstract = "(32)P-Postlabeling analysis is an ultra-sensitive method for the detection of DNA adducts, such as those formed directly by the covalent binding of carcinogens and mutagens to bases in DNA and other DNA lesions resulting from modification of bases by endogenous or exogenous agents (e.g., oxidative damage). The procedure involves four main steps: enzymatic digestion of the DNA sample; enrichment of the adducts; radiolabeling of the adducts by T4 kinase-catalyzed transference of (32)P-orthophosphate from [γ-(32)P]ATP; chromatographic separation of labeled adducts; and detection and quantification by means of their radioactive decay. Using 10 μg of DNA or less, it is capable of detecting adduct levels as low as 1 adduct in 10(9)-10(10) normal nucleotides. It is applicable to a wide range of investigations, including monitoring human exposure to environmental or occupational carcinogens, determining whether a chemical has genotoxic properties, analysis of the genotoxicity of complex mixtures, elucidation of the pathways of activation of carcinogens, and monitoring DNA repair.",
