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。
