Cyanine7 NHS ester

分子式:C41H48N3BF4O4

分子量:733.64

CAS 号:2408482-09-5

外  观:深绿色固体

产品特性:

胺反应性花青7,近红外荧光染料,是Cy7®的改良类似物。

NIR荧光团可用于利用生物组织的近红外窗口-增加透明性在该光谱区域中的组织允许进行体内成像。

该试剂可用于生产Cyanine7标记的生物分子,随后用于各种体内研究,以及药物设计相关实验。

Cyanine7的结构具有中心聚甲炔链的刚性设计。这种分子增强使得与母体结构相比,可将量子产率提高20%,从而提高荧光亮度。

该试剂需要有机助溶剂进行标记(请参见下面的“推荐规程”部分)。也提供水溶性Cyanine7 NHS酯,建议用于蛋白质NIR标记。
