Transfection reagent composition, lipid nanoparticles prepared from the transfection reagent composition, kits that include the transfection reagent composition, and methods for making and using lipid nanoparticles prepared from the transfection reagent composition. Lipids when dispersed in aqueous media readily form liposomes, such as unilamellar vesicles and multilamellar vesicles. Liposomes have been used successfully to encapsulate and deliver a wide range of chemicals including nucleic acids, proteins and, small molecule drugs, to cells.
