TCO (tetrazine – trans-cyclooctene) ligation is one of the fastest reactions used for bioconjugation. It is an inverse electron demand [4+2] cycloaddition that takes place between tetrazine and trans-cyclooctene or other strained olefin.

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

This reagent possesses good aqueous solubility and stability in biological environments.

TCO(四嗪 – 反式环辛烯)连接是用于生物偶联的最快反应之一。 它是在四嗪和反式环辛烯或其他应变烯烃之间发生的逆电子需求[4+2] 环加成。

Sulfo-Cyanine5 四嗪是一种带有四嗪基团的荧光团衍生物,用于基于 TCO 连接的标记。
