| Research Abstract |
In order to examine the expression of genes after transfection of genes to a body, it is quite important to construct plasmids which can transfect genes. For this purpose, instead of SV 40 Early-Promoter, which has been used by now, we constructed a novel plasmid having lac-z gene in the down stream region ofbeta-actin Promoter or CMV Promoter. As gene-carriers, we developed two types of water soluble polymers ; (1) Poly (vinyl alcohol) with tertiary aminoacetal moieties, (2) Copoly (dimethylaminopropylacrylamide-acrylamide). Using these gene carriers, the newly constructed plasmid was transfected to NIH3T3 cells, and the transfected genes expressed in high levels. These results suggest that the newly constructed plasmid is applicable to in vivo gene transfection and that the newly developed water-soluble cationic polymers is also potent as gene carriers.
