We have GFP expressed in a variety of systems, yeast, slime mold and in a
human cell cell line and use either 476 or 488 to excite and a 510 or
525bp filter for the emission depending on application. Funny things
happens under high and low laser power. Also, a nice paper in Dec PNAS, but
not flow. Have fun. JAZ

What's the excitation/emission?

I'm not sure whether the puns are intentional or not.... but I'll pretend I
didn't notice them. There is a paper in Science 263:802(1994) by Chalfie et
al
that shows GFP spectra. Excitation has a peak at 395nm with a shoulder at
470nm and fluorescence has a peak at 509nm with a shoulder at 540nm.
