See a scientific correspondence in Nature Vol 373 pg. 663-4 for the
article you ar looking for.  BTW, I have successfully expressed the
original GFP in a variety of fibroblastic and lymphoid cell lines.  I
PCR amplified only the open reading frame (there may be inhibitory
sequences in the 5' UTR) and added a Kozak translational start seqence
in the 5' primer, then cloned into a CMV promoter vector.  All these
factors seem to be involved in getting expression in lymhoid cells.  I
have not tried the improved version of GFP described in the article,
but it looks quite good.
