產(chǎn)品簡(jiǎn)介

Sulfo-Cyanine3 tetrazine,水溶Cy3
目前Cyanine系列染料以兩種異構(gòu)體的形式存在,一種是非磺化花青素(non-sulfonated cyanines),一種是磺化花青素(sulfonatedcyanine)。兩者的光譜性質(zhì)幾乎*,因此大部分應(yīng)用可相互替換。

產(chǎn)品介紹

Sulfo-Cyanine3 tetrazine

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.
