title: Site-specific formation of abasic lesions in DNA.
abstract: A method for the introduction of depurinated lesions in DNA is described, and is based on the formation of a covalent cross-link between an antisense oligonucleotide probe and the target DNA sequence followed by an unexpectedly mild thermal depurination.
