Description
Water soluble near infrared dye sulfo-Cyanine 7, an amine-reactive succinimide ester. Sulfo-Cyanine 7 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 the monitoring of the distribution of various labeled molecules in live organisms. Sulfo-Cyanine 7 NHS ester reagent allows the preparation of sulfo-Cyanine 7-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 Cyanine 7 NHS ester, soluble in organic phase, is also available.
