Hello all luciferase lovers!
I will be happy to share my experience as well, once I have something to
tell. For now, I use RSV-Luc reporter with cloned factor sites
upstream. Co- expression of my activator results in luc levels of 20
fold higher. addition of a putative dominant-negative inhhibitor of the
activator kills this activation, so I think Its a pretty good system.
My half-life question is specific for cell-cycle induction of fos-Luc
construct. That is trickier. If the half-live is really about 4.5
hours, then I may stimulate cells for 6 hours to get over the
"background" a bit.
Thqanks,
John
