LipoMaxin is a lipid-based transfection reagent that forms complex with DNA or RNA. The complex can be transfected into a variety of adherent and suspension cell lines. This reagent delivers superior transfection efficiency and improved cell viability for a wide range of hard-to-transfect and common cells. LipoMaxin has been compared to the Lipofectamine^® 3000 Transfection Reagent and shows the similar efficiency in many cell lines. LipoMaxin can be used for the transfection of both DNA and RNA into eukaryotic cells even in the presence of serum in the culture media.
