Abstract
An object of the present invention is to provide novel double-stranded RNA having an RNA interference effect, in which the cellular uptake and the resistance to enzymatic degradation are improved, without reducing the RNA interference effect. The cellular uptake and the resistance to enzymatic degradation of a complex of a polysaccharide having a β-1,3-glucan skeleton and double-stranded RNA can be significantly improved while maintaining the RNA interference effect, by fulfilling the following conditions (i) to (iii): (i) the double-stranded RNA has a sense strand consisting of a base sequence complementary to a target sequence in a target gene and an antisense strand containing a base sequence complementary to the sense strand, and the double-stranded RNA can inhibit expression of the target gene; (ii) the double-stranded RNA has a single-stranded polydeoxyadenine bound directly or via a linker to the end of at least one of the sense strand and the antisense strand; and (iii) the polysaccharide and the single-stranded polydeoxyadenine form a complex.
