AZDye 532 Alkyne (CCT-1281)

This product was previously sold as 1045 from Fluoroprobes.


AZDye™ 532 Alkyne is a bright, yellow-fluorescent, alkyne-activated probe that reacts with azides via a copper-catalyzed click reaction (CuAAC). This probe is water-soluble and its fluorescence is pH independent over a wide pH range. The brightness and photostability of AZDye 532 dyes are well suited to direct imaging of low-abundance targets.

The absorption/emission spectra of AZDye™ 532 is a perfect match to spectra of many other fluorescent dyes based on sulfonated rhodamine core, including Alexa Fluor® 532 and CF®532 Dye.

For application where the presence of copper is not acceptable, please consider our AZDye™ 532 DBCO probe for copper-less detection of azide-modified molecules.
