Expression of enhanced green fluorescent protein following delivery of EGFP plasmid to MDA‐MB‐231 (top row) and UMUC3 (bottom row) cancer cells as visualized using inverted fluorescence microscopy. The EF‐GFP plasmid was delivered using FA‐conjugated polymers, parental aminoglycoside‐derived polymers, and Lipofectamine‐3000 (0.3 µL/well); weight ratios that resulted in highest transgene expression efficacies, based on dose response studies (Figure 1), were used. Lipofectamine conditions were based on vendor's protocols. Representative images
