Abstract

A method for the detection of BPDE-d guanosine adducts using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) is described and illustrated. The results indicate that MALDI is capable of detecting two other DNA benzopyrene adducts, which are trace products formed during the synthesis of BPDE-d guanosine. This MALDI-TOFMS method offers the potential for the detection of DNA adducts in human tissue using very limited sample purification and preparation. Copyright © 2006 John Wiley & Sons, Ltd.
