Alkyne derivative of Cyanine7, a near infrared fluorophore, analog of Cy7®. The alkyne can be conjugated to a variety of azides via copper-catalyzed Click chemistry.

The dye has limited solubility in water, but it can be successfully conjugated in aqueous buffers with the addition of DMSO or DMF.

Cyanine7 的炔烃衍生物,一种近红外荧光团,Cy7® 的类似物。 炔烃可以通过铜催化的点击化学与多种叠氮化物结合。

该染料在水中的溶解度有限,但可以在添加 DMSO 或 DMF 的水性缓冲液中成功偶联。
