Abstract:Cationic liposomes are traditionally used for delivering macromolecules such as nucleic acids to mammalian and plant cells. This paper describes a novel simple and relatively inexpensive method for preparation of cationic liposomes using an ethanol injection/pressure extrusion method. The study also evaluated the utility of a colorimetric method for quantification of cationic liposomes. Binding of erythrosine dye to cationic liposomes resulted in a shift of the absorption maximum of the dye from 528nm to 549nm… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
