Cy系列属于花菁类染料，其中Cy SE是非水溶性形式，Sulfo-Cy SE是磺酸化的高水溶性形式，两者属于单反应性染料，Sulfo-Cy bis-SE是磺酸化的高水溶双反应性染料。 它们可溶于有机溶剂如DMSO、DMF等，被广泛用于标记肽、蛋白质和寡聚体等生物分子，特别是精细蛋白和易于变性的蛋白。 Cy系列染料除了用于标记生物分子外，也常被用于动物活体成像。由于细胞和组织的自发荧光在近红外波段小，而近红外光在生物组织中的穿透深度较大，因此在检测复杂生物系统时，Cy系列染料能提供更高的特异性和灵敏度。同时，Cy系列染料还拥有紫外光区染料和同位素标记无法具备的生物安全性，有利于在活生物体中监控各种标记分子的分布。 注意事项： 1. 溶解后的Cy SE溶液最好立即使用。 2. 荧光染料均存在淬灭问题，请尽量注意避光，以减缓荧光淬灭。 3. 为了您的安全和健康，请穿实验服并戴一次性手套操作。 应用范围： 蛋白核酸标记染料 Product introduction： The Cy series belongs to the cyanine dye family, among which Cy SE is an insoluble form, Sulfo Cy SE is a sulfonated high water soluble form, and both belong to the monoreactive dye family. Sulfo Cy bis SE is a sulfonated high water soluble dual reactive dye. They are soluble in organic solvents such as DMSO and DMF, and are widely used for labeling biomolecules such as peptides, proteins, and oligomers, especially fine proteins and proteins that are prone to denaturation. In addition to being used for labeling biological molecules, Cy series dyes are also commonly used for animal imaging in vivo. Due to the small spontaneous fluorescence of cells and tissues in the near-infrared band and the greater penetration depth of near-infrared light in biological tissues, Cy series dyes can provide higher specificity and sensitivity when detecting complex biological systems. At the same time, the Cy series dyes also have biological safety that cannot be achieved by ultraviolet light zone dyes and isotope labeling, which is conducive to monitoring the distribution of various marker molecules in living organisms. Matters needing attention： 1. 溶解后的Cy SE溶液最好立即使用。2. 荧光染料均存在淬灭问题，请尽量注意避光，以减缓荧光淬灭。3. 为了您的安全和健康，请穿实验服并戴一次性手套操作。 Scope of application： Protein nucleic acid labeling dye
