AZDye? 488 Alkyne (Alexa Fluor? 488 Alkyne equivalent) 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. 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? 488A. AZDye? 488 Alkyne can be used a less expensive alternative to Alexa Fluor? 488 Alkyne.
