With an epifluorescence microscope, DsRed is significantly brighter
and much more resistant to photobleaching than GFP/EGFP; I imagine as
such it is much better than EBFP as well. I have not yet tried it
with flow, but will soon.
One word of warning with DsRed: At least in E. coli, there is a very
large delay (36-48 hours) before it is visible to the eye. This is
unfortunate, as the other FPs express visibly much faster.
