摘要
Disclosed is a conjugate for gene transfer, which is capable of being used for treatment of incurable diseases, comprising an oligonucleotide intended to be transferred into target cells and a hydrophilic polymer, wherein an end of the oligonucleotide is covalently conjugated to the hydrophilic polymer. Also, the present invention discloses polyelectrolyte complex micelles formed from such a conjugate and a cationic polymer or cationic peptide. Such polyelectrolyte complex micelles can effectively transfer oligonucleotides as therapeutic agents into target cells, making it possible to obtain desired activities of the delivered oligonucleotides in target cells even when the micelles are clinically applied at a relatively low concentration. Therefore, the conjugate and the polyelectrolyte complex micelle are very useful in basic life science research and the medical field.
