The invention relates to a method of minimizing off-target effects of siRNA, comprising preparing double-stranded RNA (dsRNA) having a sense strand that is homologous to a sequence of a target gene and an anti-sense strand that is complementary to said sense strand, and having at least one pyrimidine replaced by a 5′-methyl-pyrimidine, and contacting said dsRNA with a cell capable of expressing said target gene.
本发明涉及一种使 siRNA 的脱靶效应最小化的方法,包括制备双链 RNA(dsRNA),该 RNA 具有与靶
基因序列同源的有义链和与所述有义链互补的反义链,并且至少有一个
嘧啶被 5′-
甲基嘧啶取代,然后将所述 dsRNA 与能够表达所述靶
基因的细胞接触。
