Luciferase half-life?

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.
