Can EYFP be run on FACScan?

Dear Nan,
The absorption of YFP is about half at 488nm, so you should see some signal
though it may be dim depending on the level of expression; the FL1 channel
will be the best choice for detection. You can see the details at:

The web site that I built is still there even though I have been an
independent consult in cytometry since 1 June of this year.
