DNase I protection of cSLN:pDNA complexes. (1: Control pDNA; 2: Naked pDNA incubated with DNase I; 3-5: pDNA released from cSLN:pDNA complexes following incubation with DNase I for cSLN:pDNA ratios 1:1, 2:1, and 3:1 (v:v), respectively. (Lanes A1-5 for cSLN1, lanes B1-5 for cSLN2, lanes C1-5 for cSLN3, and lanes D1-5 for cSLN4)
cSLN: Cationic solid lipid nanoparticle, pDNA: Plasmid DNA
