Figure 3From: Effects of size and topology of DNA molecules on intracellular delivery with non-viral gene carriersAnalysis of DNA binding to the gene carriers PEI (a), PLL (b), PLL-PA (c), and Lipofectamine-2000™ (d). Densitometric analyses of the binding results in the form of percent DNA bound were summarized as a function of increasing carrier:DNA weight ratio. The corresponding gel pictures of DNA-carrier complex were also shown.Back to article page
