the interactions of β-lactoglobulin ab in the presence of cationic surfactants such as cetyltrimethylammonium bromide and cetyltrimethylammonium p-toluenesulfonate have been investigated using a variety of experimental techniques such as conductivity, uv-vis spectrophotometry and fluorimetry. the conductivity of surfactants aqueous solutions with β-lactoglobulin shows that the cmc of cationic s...

We propose a mechanism for oligonucleotide (ODN) release from cationic lipid complexes in cells that accounts for various observations on cationic lipid-nucleic acid-cell interactions. Fluorescent confocal microscopy of cells treated with rhodamine-labeled cationic liposome/ fluorescein-labeled ODN (F-ODN) complexes show the F-ODN separates from the lipid after internalization and enters the nu...

OBJECTIVE To compare the efficiency of intra-arterial, intraportal, and intravenous administration of cationic lipid emulsion/DNA complex, as used for gene transfer to rat liver. MATERIALS AND METHODS DNA-carrier complex for the in-vivo experiment was prepared by mixing DNA and a cationic lipid emulsion. According to the administration route used (intra-arterial, intraportal, or intravenous),...

DiC14-amidine (N-t-butyl-N°-tetradecylaminopropionamidine) is a cationic lipid used as transfection agent in vitro [1] and as a vector for in vivo gene therapy applications. DiC14-amidine molecules assemble in a liposomal structure (transition temperature: 23C-critical micelle concentration: 10-7 M). Compared to other cationic lipids, diC14-amidine does not require a helper lipid. This property...
