AZDye 555 Alkyne

AZDye™ 555 Alkyne is a water-soluble, bright, orange-fluorescent dye with excitation ideally suited for the 532 nm or 555 nm laser lines and visualized with TRITC (tetramethylrhodamine) filter sets. AZDye™ 555 Alkyne reacts with azides via a copper-catalyzed click reaction (CuAAC) to form a stable triazole linker.

AZDye™ 555 is structurally similar to Alexa Fluor® 555, and spectrally is almost identical to Cy3 Dye, Alexa Fluor® 555, CF® 555 Dye, or any other Cyanine3 based fluorescent dyes. AZDye™ 555 Alkyne can be used as less expensive alternative to Alexa Fluor® 555 Alkyne.

For application where the presence of copper is not acceptable, please consider our AZDye™ 555 DBCO or Cy3 DBCO probes for copper-less detection of azide-modified molecules.
