Fig. 6From: A flow cytometric approach to study the mechanism of gene delivery to cells by gemini-lipid nanoparticles: an implication for cell membrane nanoporationRFP expression in PAM212 cells with different status of cell membrane integrity. a The status of cell membrane integrity was determined based on the intensity of Sytox red DNA stain using flow cytometry; R1 highly-porated cells, R2 partially-porated cells, R3 intact cells, R4 debris and cell fragments. b Stacked bar graph presents the membrane status of cells expressing RFP after transfection by Lipofectamine Plus or 18-3-18 GL-NPsBack to article page
