Amine reactive Cyanine7, near infrared fluorescent dye, an improved analog of Cy7®.

NIR fluorophores can be used to take advantage of near infrared window of biological tissues – increased transparency of tissues in this spectral region allows to carry out in vivo imaging.

This reagent can be utilized to produce Cyanine7-labeled biomolecules for subsequent use in various in vivo research, and drug design related experiments.

The structure of Cyanine7 features rigidized design of central polymethyne chain. This molecular reinforcement allows to increase quantum yield by 20% compared with parent structure, increasing fluorescence brightness.

胺反应性 Cyanine7,近红外荧光染料,Cy7® 的改进类似物。

NIR 荧光团可用于利用生物组织的近红外窗口 – 在该光谱区域增加组织的透明度允许进行体内成像。


Cyanine7 的结构具有中央聚甲炔链的刚性设计。 与母体结构相比,这种分子增强可以将量子产率提高 20%,从而增加荧光亮度。

This reagent requires organic co-solvent for the labeling (please see Recommended Protocols section below). Water-soluble Cyanine7 NHS ester is also available, and recommended for protein NIR labeling.

该试剂需要用于标记的有机助溶剂(请参阅下面的推荐方案部分)。 也可提供水溶性 Cyanine7 NHS 酯,推荐用于蛋白质 NIR 标记。
