In vitro evaluation of the conjugates (fluorescence-labeled acetylated polyamidoamine and fluorescence-labeled acetylated polyamidoamine lung cancer targeting peptide) targeting to 293T and NCI-H460 cells determined by inverted fluorescence microscopy. The cells were incubated with the conjugates (0.5 μM) for 4 hours. 100 × (A) 293T cells incubated with fluorescence-labeled acetylated polyamidoamine. B) 293T cells incubated with fluorescence-labeled acetylated polyamidoamine lung cancer targeting peptide. C) NCI-H460 cells incubated with fluorescence-labeled acetylated polyamidoamine. D) NCI-H460 cells incubated with fluorescence-labeled acetylated polyamidoamine lung cancer targeting peptide. E) local amplification of D.
