Dear Angeline,

You may well find that if you paraffin embed you lose the fluorescence,
although you might be able to use antibodies to detect it (which of
course, opens up more problems!). we have used both fluorescence and
antibodies to detect this protein, and have managed to accomodate most
problems, (although if anyone can suggest ways to prevent non specific
staining of GFP in muscle, like other antibdies, i would be grateful!).

You should be able to see it with UV in the frozens, we certainly have
with GFP in muscle and in tumours, though we havent really looked so
much in brains...

Let me know if i can help any more,
