Lumiprobe Sulfo-Cyanine7 NHS ester

Sulfo-Cyanine7 NHS ester是水溶近红外染料sulfo-Cyanine7，是胺类活性琥珀酸亚胺酯。

Sulfo-Cyanine7是Cy7®荧光团的的改良衍生物，量子产率提高20%，并具有更好的耐光性。该染料尤其适用于NIR成像应用。

近红外荧光染料利用了生物组织在特定的波长范围里的透明度。这种方法是无损伤性的，并允许在活体内对多种已标记的生物分子的分布进行跟踪。

Sulfo-Cyanine7 NHS ester可以很轻松的标记生物分子，如：蛋白质。标记的分子可以用于后续多种研究及药物开发相关的实验。

这种染料有很高的水溶解度，尤其适用于痕量蛋白质和易变性蛋白质的标记。需有机溶剂才能溶解的非磺化的Cyanine7 NHS ester。
