Plain liposomes are extensively used as artificial cell models and for studying the interaction of various types of molecules such as peptides and proteins with the surface of the lipid membranes. Plain liposomes are also used as control formulations for many different types of drug encapsulated liposome formulations. Charged liposomes are also used in many different types of blood complement studies. Plain liposomes are available in various anionic, cationic and neutral surface charges. Plain liposomes can be unilamellar or  multilamellar.

DOTAP is a positively charged molecule and the products in Cellsome®-DOTAP-based catalog use DOPC as a matrix lipid and various amounts of cationic DOTAP lipid from 0.5% to 50% with various zeta potentials. If you are looking for DOTAP based liposomes for gene delivery, then you need to see the Genesome liposome catalog.

If you are looking for the cationic DOTAP-based liposomes for DNA/RNA delivery, please see Genesome® liposome catalog.
