Figure 4. Fluorescence microscopy, visualization of FITC-labeled, R5W3R4 (A, B), [RW]6 (C, D), [RW]5 (E, F), [RW]4 (G, H), and [RW]3 (I, J) in A459 cells. The top photos show fluorescence microscopy and the bottom bright field of A459 cells. Live cells were treated with 25 µm of peptides for 1.5 h at 37 °C. Control cells were incubated in RPMI medium without the peptides.
