An Evaluation on Transfection Efficiency of pHRE-Egr1-EGFP in Hepatocellular Carcinoma Cells Bel-7402 Mediated by PEI-MZF-NPs

Table 1

Comparison of toxicity on Bel-7402 cells transfected by means of PEI-MZF-NPs, electric perforation, and liposome over a period of 72 h (𝑥±𝑠, 𝑛=5).

Group	Optical density (OD)	Relative survival rate (%)
Negative control group	0.599 ± 0.012
PEI-MZF-NPS group	0.581 ± 0.009^b,c	97.1
Electricity perforation group	0.394 ± 0.009^a	65.8
Liposomes group	0.249 ± 0.073^a	41.5

^a𝑃<0.001 versus negative control group; ^b𝑃<0.001 versus electricity perforation group. ^c𝑃<0.001 versus liposomes group.
