Jay,
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.
