title: Design of oligonucleotides for sequence-specific triple-helix formation. Properties of oligonucleotides containing 2'-deoxyxanthosine.
abstract: Homopyrimidine-homopurine sequences are targeted by homopyrimidine oligodeoxynucleotides to form triple helix structure. Xanthine was introduced to the third strand of pyrimidine-rich 15-mer oligodeoxy-nucleotides to recognize a cytosine in the purine strand in a homopyrimidine-homopurine duplex target.
