Agarose gel electrophoresis of D-SPM/pDNA complex at different ratios following DNase treatment. Lane 1: 1 kb DNA ladder; 2, 4, and 6: D-SPM complexes at ratio 14, 16, and 18, respectively; 3, 5, and 7: D-SPM/pDNA complexes at ratio 14, 16, and 18, respectively, treated with DNase I; 8: free pDNA; 9: free pDNA treated with DNase I; 10: D-SPM only.
