AAT Bioquest's iFluor® dyes are optimized for labeling proteins, particularly antibodies. These dyes are bright, photostable, and have minimal quenching on proteins. They can be well excited by the major laser lines of fluorescence instruments (e.g., 350, 405, 488, 555, and 633 nm). iFluor® 647 dyes have fluorescence excitation and emission maxima of ~656 nm and ~670 nm respectively. The iFluor® 647 family has spectral properties essentially identical to those of Cy5® (Cy5® is the trademark of GE Healthcare). Compared to Cy5® probes, iFluor® 647 reagents have much stronger fluorescence and higher photostability. Their fluorescence is pH-independent from pH 3 to 11. These spectral characteristics make this new dye family an excellent alternative to Cy5® and Alexa Fluor® 647 (Cy5® and Alexa Fluor® are the trademarks of Invitrogen and GE Health Care). iFluor® 647 alkyne is reasonably stable and shows good reactivity and selectivity with the azido group.

Figure 1. Click chemistry is a method for attaching a probe or substrate of interest to a specific biomolecule, a process called bioconjugation. The possibility of attaching fluorophores and other reporter molecules has made click chemistry a very powerful tool for identifying, locating, and characterizing both old and new biomolecules. The classic click reaction is the copper-catalyzed reaction of an azide with an alkyne to form a 5-membered heteroatom ring, this reaction is commonly called Cu(I)-Catalyzed Azide-Alkyne Cycloaddition (CuAAC).
