The present invention relates to cationic polymeric conjugates and methods of preparing and using them as gene carriers. The cationic polymeric conjugates comprise a poly(ethylene glycol) (PEG) grafted cationic polymer and a targeting moiety(TM), wherein 0.1 to 10 mole percent of the cationic groups of the cationic polymer are substituted with PEG-TM.

Присытствыющий вымысел относит к cationic полимерным конъюгатам и методам подготовлять и использования их как несущие гена. Cationic полимерные конъюгаты состоят из гликоля) poly(ethylene (ШПЕНЬКА) привили cationic полимер и пристреливая moiety(TM), при котором заменяют от 0.1 до 10 процента моли cationic групп в составе cationic полимер с PEG-TM.
