Internalization of polyplexes delivered from coated substrates in the presence of endocytic inhibitors. Cells were cultured with the endocytic inhibitors chlorpromazine and genistein on substrates coated with (A) BSA, (B) collagen I, (C) fibronectin, and (D) FBS. Internalized fluorescence levels were normalized to fluorescence of non-inhibitor conditions for each substrate coating. Data is presented as an average of triplicate measurements ± standard deviation of the mean. A statistical significance with p < 0.05 is denoted for values with different letters
