Recent evidence supports a role for proteoglycans in polycation-mediated gene delivery.
Therefore, the interaction of glycosaminoglycans with cationic lipid-DNA complexes
(CLDCs) has been characterized using a combination of biophysical approaches. At low
ionic strength, CLDCs bind to heparin-derivatized Sepharose particles, with the ratio of
cationic lipid to DNA controlling the binding. Incorporation of the helper lipids cholesterol or
1, 2-dioleoyl-phosphatidylethanolamine increases the amount of bound CLDC. Heparin also …
