Figure 4From: Effects of size and topology of DNA molecules on intracellular delivery with non-viral gene carriersDissociation kinetics of DNA-carrier complexes using heparin sulfate as the competitive polyanion. Results are displayed as a function of the concentration of heparin added and the percent of DNA released. Shown here are dissociation of the complexes with PEI (a), PLL (b), PLL-PA (c), and Lipofectamine-2000™ (d).Back to article page
