title: Synthesis and hybridization studies on oligonucleotide-metal complex conjugates.
abstract: We synthesized a DNA oligomer with a terpyridine x Cu(II) complex-linked thymidine residue at phosphors the 5'-end. The attachment of the 5'-complex slightly enhanced the thermal stability of the DNA match-duplex. We also determined the thermal stabilities of the modified DNA duplexes and their unmodified counterparts, with a mismatched base-pair, to examine the effect of the complex on the stability.
