AZDye 488 Alkyne

AZDye™ 488 Alkyne is a bright, green-fluorescent alkyne-activated probe routinely used for imaging of low abundance azide-containing biomolecules. AZDye™ 488 Alkyne reacts with azides via a copper-catalyzed click reaction (CuAAC) to form a stable triazole linker. A probe for copper-less azide detection (AZDye™ 488 DBCO) is also available for application where the presence of copper is not acceptable.

AZDye™ 488 is a bright, and 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 blue dyes are best suited to direct imaging of low-abundance targets. AZDye™ 488 is structurally identical to Alexa Fluor® 488 Alkyne. Its absorption/emission spectra is a perfect match to spectra of many other fluorescent dyes based on sulfonated rhodamine 110 core, including DyLight® 488, Alexa Fluor® 488 and CF® 488 Dye.
