(A) Percent entrapment efficiency of pCMV-GFP in nanoplexes as a function of amount of plasmid initially added (*P<0.05, **P<0.01). (B) Size profiles for formulations H and S when empty and when containing pCMV-GFP. (C) Zeta potential values for formulations H and S when empty and when containing pCMV-GFP. (D) Electrophoretic mobility of formulations H and S when empty and when containing pCMV-GFP after disruption in sodium dodecyl sulfate aqueous solution (0.4% w/v).

Abbreviations: pDNA, plasmid DNA; pCMV-GFP, plasmid coding for the green fluorescent protein-cytomegalovirus.
