Very long-chain fatty tails for enhanced transfection.
The long chain saturated fatty acids, arachidic (C20) and lignoceric (C24), are found as components of phospholipids within mammalian cellular membranes. Although these lipids have rarely been used as components of transfection reagents, we recently demonstrated that elongation of the fatty tail beyond C18 provide a means of increasing the transfection efficiency of cationic lipids. To investig...
متن کاملStructure-activity correlation in transfection promoted by pyridinium cationic lipids.
The efficiency of the transfection of a plasmid DNA encoding a galactosidase promoted by a series of pyridinium lipids in mixtures with other cationic lipids and neutral lipids was assessed in CHO-K1 cells. We identify key molecular parameters of the lipids in the mixture - clog P, lipid length, partial molar volume - to predict the morphology of the lipid-DNA lipoplex and then correlate these ...
متن کاملCationic liposome-mediated RNA transfection.
We have developed an efficient and reproducible method for RNA transfection, using a synthetic cationic lipid, N-[1-(2,3-dioleyloxy)propyl]-N,N,N-trimethylammonium chloride (DOTMA), incorporated into a liposome (lipofectin). Transfection of 10 ng to 5 micrograms of Photinus pyralis luciferase mRNA synthesized in vitro into NIH 3T3 mouse cells yields a linear response of luciferase activity. The...
متن کاملGene Transfection in High Serum Levels: Case Studies with New Cholesterol Based Cationic Gemini Lipids
BACKGROUND Six new cationic gemini lipids based on cholesterol possessing different positional combinations of hydroxyethyl (-CH2CH2OH) and oligo-oxyethylene -(CH2CH2O)n- moieties were synthesized. For comparison the corresponding monomeric lipid was also prepared. Each new cationic lipid was found to form stable, clear suspensions in aqueous media. METHODOLOGY/PRINCIPAL FINDINGS To understan...
متن کاملBioreducible Cationic Polymers for Gene Transfection
Gene therapy holds substantial promise for the treatment of a broad class of overwhelming human diseases such as cancer and AIDS (Verma & Somia, 1997). An essential procedure in gene therapy program involves the delivery of encoded plasmid genes into the patient’s somatic cells so as to express therapeutic proteins. An ideal strategy for successful gene delivery depends on safe and efficient ge...
