Cyanine3B azide

Description

Cyanine3B azide for click chemistry conjugation with terminal alkynes via a copper-catalyzed click reaction or strained cyclooctynes via a copper-free click reaction. Cyanine3B is a yellow-emitting cyanine dye that is an improved version of the Cyanine3 fluorophore with significantly higher fluorescence quantum yield and photostability. Due to the fixed conformation, Cyanine3B has the highest emission quantum yield compared to other dyes of this wavelength. This is a non-sulfonated dye that requires an organic co-solvent DMF, DMSO, or other for efficient labeling in water.
