Lumiprobe 水溶性cy染料

Lumiprobe 水溶性Cy染料

磺化和非磺化染料都可用于标记生物分子例如DNA和蛋白质。染料之间的差异是它们的溶解性:磺基染料是水溶性的,并且它们不使用有机共溶剂用于在水性环境中的标记。它们不易于在水中聚集。
There are two varieties of cyanine dyes: non-sulfonated cyanines, and sulfonated cyanines. For many applications they are interchangeable, because their spectral properties are nearly identical. Both sulfonated and non-sulfonated dyes can be used for the labeling of biomolecules such as DNA and proteins. The difference between the dyes is their solubility: sulfo- dyes are water-soluble, and they do not use of organic co-solvent for the labeling in aqueous environment. They are less prone to aggregation in water.

Sulfo-Cyanine7 carboxylic acid is non-reactive water soluble near infrared dye.
The reagent is useful as a fluorescent marker in NIR range when attachment to other molecules is not desired. It has high hydrophilicity and aqueous solubility, improved quantum yield in NIR range, and very high molar extinction coefficient.
This reagent contains free carboxylic acid function. Pre-activated activated ester – sulfo-Cyanine7 NHS ester is also available.
