Available fluorochromes attached to Morpholinos

I like carboxyfluorescein. It is bright, it doesn’t alter how the oligo behaves, and most labs already have a fluorescein cube (filters and dichroic mirror) for their fluorescent microscopes. The down side is that fluorescein photobleaches, so you should minimize its exposure to intense light and only observe it with the microscope when you are ready to take pictures and turn off the lamp soon. Carboxyfluorescein emits green.
