Paraformaldehyde again.

Dear Flowcyte gurus,

First I would like to thank all for their good advice with
paraformaldehyde. I found this List a week ago and really appreciate the
quality of the discussion and information.

I already searched the archive for my other question, but found nothing
about it. So here is my question : I am studying the expression of
constitutive GFP in mammalian cells. GFP will leak only from dead cells
when membrane integrity is loss (personal observation). As paraformaldehyde
permeabilize the cell membrane, will the GFP expressed will be entrapped
into cells or will GFP leak with time... Is there any way to prevent the
leakage of GFP after fixation ? Does high paraformaldehyde concentration
could be the solution (4%, 6%, 8% ?).

Thank you for your help.
