AZDye™ 488 Azide is a bright, green-fluorescent, azide-activated probe that reacts with terminal alkynes via a copper-catalyzed click reaction (CuAAC). It also reacts with strained cyclooctynes via a copper-free click chemistry reaction to form a stable triazole and does not require a Cu-catalyst or elevated temperatures.

AZDye™ 488 is a bright, highly photostable, green-fluorescent probe optimally excited by the 488 nm laser line. This probe is water-soluble and its fluorescence is pH independent over a wide pH range. The brightness and photostability of AZDye™ 488 dyes are best suited to direct imaging of low-abundance targets.
