	I have noticed autofluorescence in live or fixed HT1080 fibroblast
cells that I use.  This fluorescence can be distinguished from that of GFP
because it is still visible with the rhodamine cube.  It must have a
broader spectrum of emmission than GFP.  It's still a pain, but at least
you can differentiate GFP from bkg fluorescence.
