Near-infrared, sulfhydryl reactive Cyanine7 dye, an analog of Cy7® maleimide.

This reagent allows to attach near infrared Cyanine7 dye to proteins with free sulfhydryl groups. Labeled proteins thus obtained are used in NIR bioimaging applications. NIR imaging systems can be used to visualize distribution of labeled proteins in tissues even in live organism.

近红外、巯基反应性 Cy7 染料,Cy7® 马来酰亚胺的类似物。

该试剂允许将近红外 Cyanine7 染料连接到具有游离巯基的蛋白质上。 由此获得的标记蛋白质用于近红外生物成像应用。 NIR 成像系统可用于可视化标记蛋白质在组织中的分布,甚至在活生物体中。
