Sulfo-Cy7 alkyne Usage And Synthesis

Description

Sulfo-Cy7 alkyne is water soluble cyanine containing an alkyne group. The alkyne is commonly used for azide Click-Chemistry reactions. The sulfite group increases the solubility of the compound in aqueous media.

Uses

Sulfo-cyanine7 alkyne potassium is a water-soluble near-infrared dye with a sulfonated terminal alkyne that can be used in copper-catalyzed click chemistry reactions to conjugate with azides in an aqueous environment.
