Lumiprobe Sulfo-Cyanine3 azide
Sulfo-Cyanine3 azide是用于點擊化學的水溶疊氮染料。其激發和發射波長與Cy?熒光團相同。
由于這種染料的高亮度，耐光性，再加上在水中高溶解度的特點，該染料成為點擊化學中水相標記各種分子的理想選擇。
在水相中不需有機共溶劑即可進行點擊反應（Click reaction）。該染料是為標記敏感的分子如蛋白甚至完整的生物體而設計。
該試劑是1:1混合的crystallosolvate和methanol。但不會對熒光團性能和應用有任何影響。
Sulfo-Cyanine3 azide is a water-soluble dye azide for Click Chemistry. Absorbance and emission of the dye are identical to Cy3? fluorophore.
Brightness and photostability of fluorophore, together with high water solubility, makes this reagent an ideal choice for Click chemistry labeling of various molecules in aqueous phase.
Click reaction can be carried out in pure water without need to use organic co-solvent. The reagent is designed for the labeling of sensitive molecules such as proteins, and even intact biological objects.
