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-Cyanine5.5 NHS ester 是磺化远红 Cyanine5.5 荧光团的胺反应活性酯，是 Cy5.5® 的类似物。这是标记抗体、敏感蛋白和其他需要在纯水性环境中反应或无需添加任何有机助溶剂的试剂的首选。
该染料非常适合非-侵入性体内 NIR 成像，适用于需要低荧光背景的应用。
