Crystallization processes of lipid matrices were characterized by X-ray diffractometry and differential scanning calorimetry. pDNA binding ability of SLNs and the stability of pDNA-SLN complexes with DNase I enzyme were also determined by gel electrophoresis. It was determined that all formulations became positively charged with DOTAP®R. They were able to bind DNA and were partially protective against enzyme degradation. Although additional studies are necessary, this study reveals the promising potential of this gene delivery system for gene therapy. |
