I’ve been using your cyanine7.5 amine to label some of my polymers but I can’t seem to get any signal when I test the fluorescence on the fluorometer.
I’ve been using your cyanine7.5 amine to label some of my polymers but I can’t seem to get any signal when I test the fluorescence on the fluorometer.

Possible reasons why you don't see any fluorescence signal from conjugates or the dye alone or in different solvent systems.
