Fig. 2From: Genotoxic and epigenotoxic effects in mice exposed to concentrated ambient fine particulate matter (PM2.5) from São Paulo city, BrazilRepresentative chromatograms of DNA samples obtained by HPLC-ESI-MS/MS showing a 8-oxo-7,8-dihydro-2′-deoxyguanosine (8-oxodGuo); b 1,N2-etheno-2′-deoxyguanosine (1,N2-εdGuo) and 1,N6-etheno-2′-deoxyadenosine (1,N6-εdAdo); c 5-methyl-2′-deoxycytidine (5-mC), 5-hydroxymethyl-2′-deoxycytidine (5-hmC), and 2′-deoxycytidine (dCyd). The analyses were performed with multiple reaction monitoring (MRM) by using the fragmentations specified in the images for each analyte.
