Analysis by mass tagging-MALDI-TOF-MS of DNA adducts formed when p-benzoquinone (BQ) is reacted with calf thymus DNA. Assignments: 1 (m/z 593.152 and 597.177): BH- and BH(d4)-conjugates of BQ-dCMP; 2 (607.172 and 611.196), corresponding conjugates of BQ-mdCMP; 3 (617.164 and 621.188, in inset), corresponding conjugates of BQ-dAMP; and 4 (633.156 and 637.178 in inset), corresponding conjugates of BQ-dGMP.
