產品簡介

Cyanine3 tetrazine,Cy3-四嗪
目前Cyanine系列染料以兩種異構體的形式存在,一種是非磺化花青素(non-sulfonated cyanines),一種是磺化花青素(sulfonatedcyanine)。兩者的光譜性質幾乎*,因此大部分應用可相互替換。

產品介紹

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.
