iFluor® 555 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® 555 tetrazine can be readily used to label TCO-modified biological molecules for fluorescence imaging and other fluorescence-based biological applications. The peptide and oligo conjugates prepared with iFluor® 555 dye are far superior to the conjugates of other spectrally similar dyes, such as the popular Cy3 and Alexa Fluor® 555. iFluor® 555 conjugates are significantly brighter and much more photostable than the corresponding conjugates of Cy3 and Alexa Fluor® 555 (Alexa Fluor® is the trademark of Invitrogen).
