摘要：

Identification and quantitation of covalent carcinogen-DNA adducts, an important class of biomarkers, is an integral goal in toxicological research. Since these adducts are commonly present at very low levels in in vivo samples, sensitive and specific analytical methodologies are imperative for accurate detection, characterization and quantitation. High-performance separations coupled to electrospray mass spectrometry (ESI-MS) provide the sensitivity and specificity required for the analysis of DNA adducts. This review provides an overview over the research conducted in this area, focusing on the application of HPLC-ESI-MS and CE-ESI-MS techniques for structural analysis and quantitation of modified nucleosides, nucleotides and oligonucleotides.
