In vitro evaluation of dose-dependent uptake of the conjugates (fluorescence-labeled acetylated polyamidoamine and fluorescence-labeled acetylated polyamidoamine lung cancer targeting peptide) by 293T cells (A) and NCI-H460 cells (B) determined by fluorescence-activated cell sorting. The cells were incubated with various concentrations of the conjugates for 4 hours at 37°C. C) Time-dependent uptake of the conjugates by NCI-H460 cells. The NCI-H460 cells were incubated with the conjugates at a concentration of 0.25 μM for different time. D) Uptake of the conjugates by 293T and NCI-H460 cells. The incubation conditions were 0.5 μM and four hours.
