I am interested in looking at the ROS in the cytoplasm and mitochondria using some ro-GFP probes for which I have to transfect primary hepatocytes with these plasmids. I have already tried Liposomes for this but it is not working as expected. Literature (very few papers available) says it is the best method, but I just wanted to ask whether anybody has some experience with liposomes or any other transfection method for transfecting primary hepatocytes which works best?
