POLYETHYLENE GLYCOL/POLYCATION BLOCK COPOLYMER |
| 摘要 |
<p>The invention provides block copolymers formed of poly(ethylene glycol) segments and poly(amino acid derivative) segments having side chains of at least one kind of specific amine residue. The invention also provides polyion complexes of such copolymers with polynucleotides and the like. These block copolymers are useful as carriers for in vivo delivery of active substances such as DNA.</p> |
