I only have experience using GFP (eGFP from Clonentech), and for us the
standard 2% PFA, 0.05% Saponin didn't destroy our GFP Staining, and GFP
doesn't leak out of the cells. Haven't tried intra cellular staining on the
same time, could be tricky of course because GFP = green fluorescence, so
you would have to use PE or a conjugate for the intracellular staining..
although this works in some cases, background could be higher than with
FITC...
Sorry that I can't help you more, but maybe others have more experience in
this...
Cheers Matthias
