After over a year of trying various different GFP expression vectors in
BAEC and NIH 3T3 I'm still no closer to getting any fluorescence. I do
get transcription though (RT PCR works fine, but PCR on the RNA gives
nothing), and I can detect it (from a slide from Clontech, and from
bacterial expression) so I don't think it's likely to be a promoter
problem. I would put money on it that it's a problem either with
translation of the RNA to give a protein with a functioning fluorescent
moiety or rate of degradation of normal GFP. It may be a problem with
formation of the fluorophore after normal production of GFP. The most
puzzling thing is why do some people get it to work and others don't?
