Abstract
2-Deoxyribonolactone (L) is an oxidized abasic lesion that is produced by a variety of DNA damaging agents. It exhibits unique biological effects with respect to its proclivity to form DNA-protein cross-links and promutagenic base pairs. Recent evidence suggests that the levels of this lesion caused by oxidative stress are underestimated. We have developed a simple, selective method for detecting subpicomole amounts of L in DNA. The method takes advantage of the selective reaction of the butenolide (2) derived from β-elimination from L with a biotinylated derivative of cysteine. This method will be useful for analyzing the levels of this oxidized abasic site in DNA.
