Aldehyded Dextran and ε-Poly(L-lysine) Hydrogel as Nonviral Gene Carrier

Figure 2

Gene transfection into 293 cells. (a), (b), and (c): results of gene transfection in plasmid of 2 μg. (d), (e), and (f): results of gene transfection in plasmid of 16 μg. (a) and (d) were carried out by only plasmid, and (b) and (e) were carried out by using PLL as a gene carrier, for the purpose of controls. (c) and (f) were carried out by using ald-dex/PLL as a gene carrier.
