Can the pcDNA5/FRT/TO vector be used for transient overexpression? - (Jul/07/2014 )
I have my gene of interest in pcDNA5FRT/TO and would like to generate a stable cell line. Before generating the stable line, however, I would like to test expression by transient transfection.
Can the pcDNA5FRT/TO vector be used for transient transfection? If so, do I need to add doxycycline to induce expression (as would be done with a stable line ...)? In a couple of papers that I found, addition of doxycyclin during transient overexpression of a construct in pcDNA5/FRT/TO was not specifically mentioned.
Yes you do need to add dox. The FRT/TO plasmid has two copies of the tet repressor inserted inside the promoter region, which repress transcription unless Dox is present.
