| abstract |
The purpose of the present invention is to increase the amount of oligonucleic acid transported into the cytoplasm by bringing about an efficient interaction of a cell uptake promoter with a target cell. An oligonucleic acid conjugate according to the present invention comprises a dendritic polymer, a plurality of oligonucleic acids, one or a plurality of cell uptake promoters, and one or a plurality of hydrophilic linkers. Each oligonucleic acid is bonded to the dendritic polymer directly or through a linker, and each cell uptake promoter is bonded to the dendritic polymer through the hydrophilic linker. |
