Intracellular kinetics of polypeptide/YOYO-1-DNA polyplexes. (A) Cellular uptake of polyplexes (N/P = 10) in COS-7 cells at 4 °C or in the presence of various endocytic inhibitors. (B) Transfection efficiencies of polyplexes (N/P = 10) at 4 °C and 37 °C in COS-7 cells. (C) Cell uptake level of FITC-Tris in HeLa (C) and COS-7 (D) cells following co-incubation with the polypeptides for 2 h at 37 °C. (E) CLSM images of HeLa cells following incubation with G6/YOYO-1-DNA polyplexes (N/P = 10) at 37 °C for 4 h. Bar represented 20 μm.
