摘要

PCT No. PCT/NL96/00324 Sec. 371 Date Jun. 30, 1997 Sec. 102(e) Date Jun. 30, 1997 PCT Filed Aug. 16, 1996 PCT Pub. No. WO97/07226 PCT Pub. Date Feb. 27, 1997The present invention to a synthetic transfection system comprising as a carrier a cationic, water dispersible polyphosphazene. In addition, it relates to a method for introducing DNA fragments in target cells, comprising contacting these DNA fragments with a polyphosphazene which is at least partially substituted with cationic substituents and subsequently contacting the obtained transfection system with target cells. Finally, the invention involves the use of a polyphosphazene which is at least partially substituted with cationic substituents as a transfection vehicle.
