abstract：:Applications of oligodeoxynucleotides to modulate gene expression have been the subject of much recent research. We have sought to develop a method to permanently inactivate a gene, or potentially kill cells containing abnormal genes. In this report, we show that a DNA intercalator conjugated to a triplex-forming olig...
