Cyanine5 alkyne for Click Chemistry, an analog of Cy5® alkyne. With this product, deeply colored, and photostable Cyanine5 fluorophore can be attached to various molecules via Click Chemistry reaction with azides.

This alkyne is non-water soluble, but it can be dissolved in DMF or DMSO prior to reaction, and added to aqueous reaction mixture. With our labeling protocol, the labeling reaction is very efficient, and high-yielding.

Various substrates bearing azides can be used for the labeling, including azido-labeled biomolecules, polymers, and solid surfaces.

Cyanine5 炔烃用于 Click Chemistry,是 Cy5® 炔烃的类似物。 使用该产品,颜色深且光稳定的 Cyanine5 荧光团可以通过与叠氮化物的 Click Chemistry 反应连接到各种分子上。

这种炔烃不溶于水,但它可以在反应前溶解在 DMF 或 DMSO 中,然后加入到含水反应混合物中。 使用我们的标记方案,标记反应非常有效且产量高。
