| 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. |

| Paper: Site Selective Antibody-Oligonucleotide Conjugation via Microbial Transglutaminase. |
https://www.mdpi.com/1420-3049/24/18/3287 This paper describes using a microbial transglutamase to put an azide group in a peptide onto the terminal carboxylic acid of an antibody protein, then using Cu-free click chemistry to affix an antisense oligo at that site. They didn't use Morpholinos, but in principle one could. |
