阳离子脂质体介导转染法是一种新的高效转染技术 ,已逐渐成为介导核酸进入真核细胞的标准方法。但由于大多数的阳离子脂质体的血清稳定性差 ,且阳离子脂质体与体内网状内皮细胞系统的关系不明 ,在一定程度上限制了其体内的应用 Cationic liposome-mediated transfection is a new and efficient transfection technique that has gradually become the standard method for mediating the entry of nucleic acids into eukaryotic cells. However, the majority of cationic liposomes have poor serum stability and the relationship between cationic liposomes and the reticuloendothelial system in vivo has been limited, which limits their application in vivo to a certain extent
