While a popular method for delivering DNA or RNA into cells may be through liposome-based reagents, other non-liposomal kits and reagents are also available on the market. Such methods may be preferable in cases where liposomal reagents have proven ineffective. These commercial non-liposomal transfection reagents have similarly been reported to feature low toxicity, high efficiency, simplicity, reproducibility, and compatibility with a wide range of cell types.
