Association of PEI/DNA complexes onto protein-coated substrates. The amount of DNA bound to the surfaces with (A) different protein coatings and (B) different fibronectin densities. The amount of DNA that associated with cells for delivery from substrates with (C) different protein coatings and (D) different fibronectin densities. 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
