Sulfo-Cyanine7.5 dicarboxylic acid
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。

Sulfo-Cyanine7.5 dicarboxylic acid

產(chǎn)品簡(jiǎn)介

Sulfo-Cyanine7.5 dicarboxylic acid is a bifunctional near infrared fluorescent dye with two carboxylic acid groups.

The reagent is useful as a cross-linker that is NIR emitting. The carboxylic acid groups can be activated by carbodiimide chemistry.
