Cyanine3 tetrazine,Cy3-四嗪
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

Cyanine3 tetrazine

Cyanine3 tetrazine is a fluorescent dye with tetrazine moiety for a conjugation reaction called TCO (trans-cyclooctene) ligation. Actually, tetrazines react not only with trans-cyclooctenes, but also with (methyl)cyclopropenes and strained non-benzo-fused cycloalkynes.

Cyanine3 is a moderay hydrophobic dye, enabling labeling in non-aueous environment as well as in aueous media containing some organic co-solvent like acetonitrile or DMSO. For reactions in purely aueous media, a sulfonated version of this reagent is available.
