Water soluble near infrared dye sulfo-Cy7, an amine-reactive succinimide ester.
Sulfo-Cy7 is an improved analog of Cy7® fluorophore with quantum yield improved by 20%, and higher photostability. This fluorescent dye is especially useful for NIR imaging.
Near infrared fluorescent imaging takes advantage of transparency of biological tissues at particular range of wavelengths. The method is non-destructive, and allows to monitor distribution of various labeled molecules in live organisms.
Sulfo-Cyanine7 NHS ester reagent allows to prepare sulfo-Cyanine7-labeled biomolecules, such as proteins, with ease. Dye labeled molecules can be subsequently used for various research and drug design related experiments.
This reagent has high water solubility, and is especially useful for the labeling of delicate proteins, and proteins prone to denaturation. Non-sulfonated Cy7 NHS ester soluble in organic phase is also available.
水溶性近红外染料 sulfo-Cy7，一种胺反应性琥珀酰亚胺酯。
Sulfo-Cy7 是 Cy7® 荧光团的改进类似物，量子产率提高了 20%，光稳定性更高。 这种荧光染料对近红外成像特别有用。
近红外荧光成像利用特定波长范围内生物组织的透明度。 该方法是非破坏性的，可以监测活生物体中各种标记分子的分布。
Sulfo-Cyanine7 NHS 酯试剂可以轻松制备磺基-Cyanine7 标记的生物分子，例如蛋白质。 染料标记的分子随后可用于各种研究和药物设计相关实验。
该试剂具有高水溶性，特别适用于标记精细蛋白质和易于变性的蛋白质。 也可提供可溶于有机相的非磺化 Cy7 NHS 酯。
