iFluor® 594 TCO

The tetrazine-trans-cyclooctene (TCO) ligation constitutes a non-toxic biomolecule labeling method of unparalleled speed. A tetrazine-functionalized molecule reacts with a TCO-functionalized molecule, forming a stable conjugate via a dihydropyrazine moiety. This has gained popularity due to its extremely fast kinetics. AAT Bioquest offers a group of tetrazine- and TCO-containing dyes for exploring various biological systems that can use this powerful click reaction. iFluor® 594-TCO can be readily used to label tetrazine-modified biological molecules for fluorescence imaging and other fluorescence-based biological applications. The conjugates prepared with iFluor® 594 dye have spectral properties almost identical to the popular Cy3.5 and Alexa Fluor® 594. In most cases, antibody conjugates prepared with iFluor® 594 tend to have lower background than the spectrally similar dye conjugates, such as Cy3.5 and Alexa Fluor® 594 (Alexa Fluor® is the trademark of Invitrogen).
