Fig. 1From: A flow cytometric approach to study the mechanism of gene delivery to cells by gemini-lipid nanoparticles: an implication for cell membrane nanoporationEffect of GL-NPs on the viability of PAM212 cells measured by MitoTracker staining and flow cytometry. Results are expressed as the mean of cell viability index ± standard deviation compared to the untreated control (as 100 %). Asterisks represent LSD post hoc statistical significance compared to Lipofectamine Plus (P < 0.05). Bar charts represent mean ± SD, n = 4Back to article page
