I have a trial for transient transfection to ATL-16T cell-line by the electroporation. But it is in vain. So I wish to know about the "cationic polymer" to use to transfect the DNA(plasmid) to cultured ATL-16T. Do you know the best reagent to achieve this work ? please responed to: hz6h-nitu at asahi-net.or.jp Hiroyuki Naito Narita/Chiba/Japan
