Cyanine3 alkyne is a fluorophore ready for the use in Click Chemistry reaction.

With this reagent, bright and photostable Cyanine3 reporter, an analog of Cy3®, can be attached to nearly any molecule bearing azide group.

This alkyne is non water-soluble. However, when used with organic co-solvent (DMSO or DMF), this dye can be efficiently attached to water-soluble molecules such as proteins, or peptides.

Cy3 炔烃是一种可用于 Click Chemistry 反应的荧光团。

使用该试剂,明亮且光稳定的 Cyanine3 报告基因(Cy3® 的类似物)可以连接到几乎任何带有叠氮基的分子上。

这种炔烃是非水溶性的。 然而,当与有机共溶剂(DMSO 或 DMF)一起使用时,这种染料可以有效地附着在水溶性分子上,例如蛋白质或肽。
