CalFluor 555 Azide is a fluorogenic azide probe that is activated by Cu-catalyzed or metal-free click reaction. This azide probe is not fluorescent until it is reacted with alkynes. CalFluor 580 Azide is a water-soluble probe, and its excitation band is a good match for the 532 nm or 555 nm laser lines.
