TCO ligation is a reaction that takes place between a tetrazine and a strained olefin, such as trans-cyclooctene.
This tetrazine bears a fragment of near infrared dye, Cyanine7. This NIR fluorophore is especially useful for in vivo imaging.
TCO 连接是在四嗪和应变烯烃（例如反式-环辛烯）之间发生的反应。
这种四嗪带有一个近红外染料的片段，Cyanine7。 这种 NIR 荧光团对于体内成像特别有用。
