iFluor® 647 Tetrazine
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® 647 tetrazine can be readily used to label TCO-modified biological molecules for fluorescence imaging and other fluorescence-based biological applications. The conjugates prepared with iFluor® 647 dye have spectral properties almost identical to the popular Cy5 and Alexa Fluor® 647. In most cases, antibody conjugates prepared with iFluor® 647 tend to have a higher signal/background ratio than the spectrally similar dye conjugates, such as Cy5 and Alexa Fluor® 647 (Alexa Fluor® is the trademark of Invitrogen).
