Abstract

Oligonucleotides containing internal triazole-3'-LNA linkages bind to complementary RNA with similar affinity and specificity to unmodified Oligonucleotides, and significantly better than Oligonucleotides containing triazole alone. In contrast LNA on the 5'-side of the triazole does not stabilise duplexes. Triazole-LNA confers great resistance towards enzymatic degradation relative to LNA alone.
