Lipofectamine™ 2000 CD (Chemically Defined) Transfection Reagent is a proprietary animal origin-free formulation for transfecting nucleic acids into eukaryotic cells. Using Lipofectamine™ 2000 CD reagent for transfection provides the following advantages:

? Highest transfection efficiency in many cell types and formats.
? The animal origin-free formulation ensures that mammalian cell culture and bioproduction processes are free of animal-derived materials.
? DNA-Lipofectamine™ 2000 CD complexes can be added directly to cells in culture medium.
? It is not necessary to remove complexes or change/add medium after transfection, but complexes may be removed after 4–6 hours.
