Alcohol fixation will rapidly destroy GFP fluorescence.  I use 1/20th
volume of formalin for 5 minutes at RT.  Cells will remain fluorescent for
several days stored in PBS at 4 C.  WT GFP is essentially useless.  Human
codon bias optimized S65T (or other enhanced) GFP is highly recommended
for FACS w/ human cells.
