EGFP does have some fluorescence when excited with UV light (much less
than 488 excitation but about the same as wt GFP) so if you have
enough GFP expressed you may be able to visualize & photograph under
I have been told you can put the excitation filter from a fluorescence
microscope in front of a light source used for dissecting microscopes
to get blue light to illuminate macroscopic samples. You then view
through the emission filter. I have not actually seen the set up but
may be someone who has done this can post more details.
