Abstract

We describe three applications of FRET technique to analyze structural and thermodynamic properties of cationic lipids and their complexes with DNA: (1) Lipid mixing assay to determine the degree to which individual vesicles undergo fusion upon complex formation. (2) DNA binding assay to obtain cationic lipid–DNA binding curves for thermodynamic analysis or binding stoichiometry characterization. (3) DNA spacing assay to determine changes in DNA packing in the multilamellar lipoplex particle.
