Tetrazine – trans-cyclooctene ligation is among the fastest bioconjugation reactions known to date.
This water soluble sulfo-Cyanine3 derivative contains methyltetrazine moiety for the coupling with trans-cyclooctenes. Methyltetrazines possess optimal stability at physiological pH, while maintaining extremely high reactivity towards cyclooctenes.
The fluorophore is bright, photostable, and is also very well visible with naked eye.
四嗪-反式-环辛烯连接是迄今为止已知最快的生物偶联反应之一。
这种水溶性磺基-Cyanine3 衍生物含有甲基四嗪部分，用于与反式环辛烯偶联。 甲基四嗪在生理 pH 值下具有最佳稳定性，同时对环辛烯保持极高的反应性。
荧光团明亮、光稳定，而且肉眼也能很好地看到。
