To investigate the cytotoxicity of the homemade peptide cationic liposome CDO14 and its efficacy of RNA interference(RNAi). MTT method was used to determine the cytotoxicity of the liposome to a human lung cancer cell line Luc-A549 that can express luciferase stably. Luciferase si RNA(Luc-si RNA) was transfected into Luc-A549 cells by CDO14. Contents of luciferase in the transfected cells were detected by luminous instrument and contents of total protein in these cells were detected by BCA method. Nude mice...
