Transfection efficiency of D-SPM/pCIKLux complex at various weight-mixing ratios with 0.5  𝜇 g pCIKLux in COS-7 cells. PEI was used as the positive control. Luciferase expression was measured as RLU/mg protein after 48 h posttransfection in serum-free condition. Luciferase expressions significantly higher than PEI are denoted by asterisks (*) ( 𝑃 < . 0 5 ) while from untreated are denoted by dagger () ( 𝑃 < . 0 5 ). Data are presented as mean ± S. E. M of experiments conducted in triplicate.
