Effects of the charge ratios of TC-1-12-based mRNA lipoplexes on cytotoxicity in HeLa cells transfected with the FLuc mRNA lipoplexes. FLuc mRNA lipoplexes were prepared using the MEI and TFH methods at charge ratios of 1:1 to 6:1, transfected into HeLa cells, and incubated for 24 h. Lipofectamine MessengerMAX was used as a control. Each value is represented as the mean ± standard deviation (n=5 for 5:1 (MEI), 1:1 (TFH), and 3:1 (TFH), and n=6 for other groups). *P<0.05, **P<0.01 and ***P<0.001 vs. TFH method. TC-1-12, 11-((1,3-bis(dodecanoyloxy)-2-((dodecanoyloxy)methyl)propan-2-yl)amino)-N,N,N-trimethyl-11-oxoundecan-1-aminium bromide; FLuc, firefly luciferase; MEI, modified ethanol injection; TFH, thin-film hydration.
