FAM tetrazine,绿光荧光染料标记四嗪
产品介绍
FAM tetrazine, 5-isomer
Tetrazine (methyltetrazine) derivative of fluorescein, pure 5-isomer.
Tetrazines are reactive heterodiene ponents 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.
