GFP fluorescence- mounting soln

Hello Nacha, 

Normally we're using something called "Permafluor". But it seems to 
me that it quenches GFP quite much, too. At least I can see strongly 
fluorescent cells and run lots of sections with the confocal without 
getting too much blecahing. 
For short observations I'd recommend PBS/glycerol with or without 5% 
n-propylgallate (as antifade). 
You might know that acetone or methanol are killing GFP fluorescence. 
So either 3,7% formaldehyde for 10 min or even nothing (you have to 
view your cells immediately then) are suitable. 

Good luck and happy GFPing!
