Abstract:
Oligodeoxynucleotide (ODN) composed of 15 nucleotides was modified at 5'-terminal phosphate with hexylamine linker and chemically activated poly(ethylene glycol). This derivative showed improved characteristics in terms of enzymatic stability, binding activity, and in vivo retention in mouse. The data are discussed in comparison with those of corresponding unmodified and phosphorothioate ODNs.
