Patent Images
1. A composition suitable for effecting gene transfer, consisting of:
- (a) one or more genetic materials chosen from the group consisting of DNA and RNA,(b) liposomes consisting of (1) PEG, (2) a steroid, (3) a charged lipid component, (4) genetic material and (5) a carrier liquid,(c) one or more polymer particles selected from the group consisting of nanoparticles, starch particles, gelatin, and Poloxamer,(d) contrasting agent selected from the group consisting of iodine-, gadolinium-, magnetite- and fluorine-containing contrasting agent, and(e) at least one component that assists in packing DNA more tightly.

28. A composition suitable for effective gene transfer consisting of:
-
(a) one or more genetic materials chosen from the group consisting of DNA and RNA; (b) liposomes consisting of (1) PEG, (2) steroid, (3) a charged lipid component, (4) genetic material, and (5) a carrier liquid; (c) one or more polymer particles selected from the group consisting of nanoparticles, starch particles, gelatin and Poloxamer; (d) a contrasting agent selected from the group consisting of iodine-, gadolinium-, magnetite-, and fluorine-containing contrasting agents; (e) at least one component that assists in packing DNA more tightly; and (f) anti-Ki-67-immune PEG liposomes or anti-CEA PEG liposomes, wherein the liposomes are present in at least one form selected from the group consisting of small unilamellar vesicles (SUV), large unilamellar vesicles (LUV), reverse phase evaporation vesicles (REV, mulitlumellar vesicles (MLV) and 3β
N-(N,N′
