Which is the best dye that can be conjugated with carboxyl group in PEG for confocal microscopy?

10 October 2016 1 3K Report

I have nanoparticles with PEG-COOH and am looking for a dye that can be conjugated to -COOH group to observe the cellular uptake through Confocal microscopy. I would be grateful to you if you suggest me on this layman question.

Thank you so much.
