摘要: The invention relates to a double-stranded RNA (dsRNA) molecule comprising between about 15 base pairs and 40 pairs, at least one 5′-methyl-pyrimidine 2′—O-methyl ribonucleotide, methods of using such modified dsRNA increase stability siRNA when in contact with biological sample, reduce off-target effects interferon responsiveness (IFN) the molecule.
