Efficient delivery of siRNA into lung adenocarcinoma cells. (A): Detection of transfection efficiency by flow cytometry. Transfection efficiency was maintained at over 85% for 6 h post-transfection. (B): Detection of transfection efficiency by fluorescence microscopy. High efficiency of transfection with fluorescent siRNA (green) in A549 cells were easily identified for 48 h post-transfection (×100).
