Application

Photoactivatable rhodamine derivative functionalized with a PEG azide. The azide functionality can be used to conjugate this caged rhodamine to alkyne or cycloalkyne containing compounds or biomolecules using the azide-alkyne cycloaddition click chemistry reaction. The ortho-Nitroveratryloxycarbonyl (NVOC) cages can be removed upon irradiation with UV light, restoring the fluorescence of the base dye. NVOC has an absorption max at ~350 nm and has been shown to be cleaved at 350 nm, 405 nm and 420 nm.

Q-Rhodamine λ(ex) = 537 nm, λ(em) = 556 nm.
