K. Yamana et al., SYNTHESIS AND BINDING-PROPERTIES OF OLIGONUCLEOTIDES CONTAINING AN AZOBENZENE LINKER, Nucleosides & nucleotides, 17(1-3), 1998, pp. 233-242
Incorporation of an azobenzene-4,4'-diamide group via a linker arm int
o the 3'-hydroxyl function of one oligonucleotide segment and the 5'-O
H of other oligonucleotide has been described. The binding of the olig
onucleotides containing the azobenzene linker was investigated by UV m
elting behaviors. The azobenzene linker has been shown to be useful as
an effective bridge for stabilizing hairpin duplex and triplex.
