Sulfo-Cyanine7.5 alkyne,水溶Cy7.5-alkyne
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-Cyanine7.5 alkyne

Sulfo-Cyanine7.5 is a near infrared, sulfonated cyanine dye with rigidized trimethylene chain. The fluorophore is structurally very similar to indocyanine green (ICG) dye that has been approved for human use. However, the dye has an improved uantum yield because of its rigidized structure.

This is an alkyne derivative for copper catalyzed Click chemistry.
