Product Introduction

5-JOE Alkyne is a fluorescent labeling reagent featuring a 5-carboxy-4',5'-dichloro-2',7'-dimethoxyfluorescein (5-JOE) fluorophore conjugated to an alkyne functional group. The alkyne moiety enables bioorthogonal click chemistry reactions, particularly copper-catalyzed or strain-promoted azide-alkyne cycloaddition, allowing selective and efficient labeling of biomolecules. It is used in oligonucleotide modification, surface functionalization, and bioconjugation applications.
