Sulfo-Cyanine5.5 NHS ester is an amine reactive activated ester of sulfonated far red Cyanine5.5 fluorophore, an analog of Cy5.5®. This is a reagent of choice for the labeling of antibodies, sensitive proteins, and others which require reactions in purely aqueous environment, or without any significant additions of organic co-solvents.
The dye is well suitable for non-invasive in vivo NIR imaging, and for the applications requiring low fluorescent background.
Sulfo-Cy5.5 NHS 酯是磺化远红 Cy5.5 荧光团（Cy5.5® 的类似物）的胺反应活性酯。 这是标记抗体、敏感蛋白质和其他需要在纯水环境中反应或无需大量添加有机助溶剂的试剂的首选试剂。
该染料非常适用于非侵入性体内近红外成像，以及需要低荧光背景的应用。
