Sulfo-Cy5 tetrazine

Sulfo-Cyanine5 tetrazine is a fluorophore derivative bearing a tetrazine group for the TCO-ligation based labeling.

TCO (tetrazine - trans-cyclooctene) ligation is one of the fastest reactions used for the bioconjugation. It is an inverse electron demand [4+2] cycloaddition that takes place between tetrazine and trans-cyclooctene or other strained olefin.This reagent possesses good aqueous solubility and stability in biological environments.
