Agarose gel electrophoresis of plasmid NP-DNA complex and corresponding three-dimensional projection plot of band intensities. (a) Agarose gel electrophoresis of plasmid DNA and NP complex with various DNA/NP mass ratios. (b) Corresponding three-dimensional projection plot of band intensities of the same gel as in (a). Results were obtained using image analysis software. Plasmid DNA and various amounts of NPs were mixed, and the mass ratio is indicated above each lane (pure plasmid DNA in the rightmost lane).
