CF555 azide reacts with alkyne to form 1,2,3-triazole by copper(I) catalyzed 1,3-dipolar Huisgen cycloaddition. It could also undergo Staudinger ligation with phosphine containing compound. CF555 dye is bright and photostable, and particularly useful for labeling antibodies. The absorption and emission spectra of CF555 are similar to those of Alexa Fluor® 555 or Cy®3.
