FAM tetrazine,5-isomer,荧光素-四嗪
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.
