Application

This special UV active chromophore is ideal for imaging purposes after conjugation to biomolecules. It emits fluorescence only after the click reaction when its electron system is expanded. Therefore no background signal is expected for the unreacted compound. λabs 404 nm (after click reaction), λem 477 nm (after click reaction ).

Molecular imaging enables visualization of specific molecules in vivo and without substantial perturbation to the target molecule's environment. Glycans are appealing targets for molecular imaging but are inaccessible with conventional approaches. Classic methods for monitoring glycans rely on molecular recognition
