Efficient cellular recognition of Apt-NS to A549 cells. A Flow cytometry analysis of A549 and HELF cells for the internalization of Apt-NS. B Quantitative analysis of the mean fluorescence intensity of each group in (A) (n = 3). 10,000 events were recorded for each sample assay. Statistical analysis: ***P < 0.001. (C) CLSM images of A549 and HELF cells treated with Apt-NS (red). Nucleus are stained blue. Scale bar is 25 μm. D Quantitative analysis of the mean fluorescence intensity of each group in (C) (n = 3). Statistical analysis: ***P < 0.001
