We report a new method for dU detection in genomic DNA combined with UNG excision and fluorescent probe labeling. UNG can remove uracil bases to introduce abasic sites, which can react with NRNO to produce intense fluorescence because of the inhibition of the PET effect. It can also cause the polymerase extension to stop to provide details of dU site information.
