Tetrazine (methyltetrazine) derivative of fluorescein, pure 5-isomer.
Tetrazines are reactive heterodiene components for [4+2] inverse electron demand Diels-Alder reaction (ied-DA) with strained cycloalkenes (trans-cyclooctenes, cyclopropenes). This reaction is also called TCO (tetrazine-cyclooctene) ligation. The reaction is among the fastest bioconjugation reactions.
荧光素的四嗪（甲基四嗪）衍生物，纯 5-异构体。
四嗪是与应变环烯烃（反式-环辛烯、环丙烯）发生 [4+2] 逆电子需求 Diels-Alder 反应 (ied-DA) 的反应性杂二烯组分。 该反应也称为 TCO（四嗪-环辛烯）连接。 该反应是最快的生物共轭反应之一。
