Sulfo-Cyanine7 NHS ester Chemical Properties,Usage,Production
Description
Water-soluble near-infrared dye sulfo-Cyanine7, an amine-reactive succinimide ester.
sulfo-Cyanine7 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 the transparency of biological tissues at a particular range of wavelengths. The method is non-destructive and allows to monitor of the 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 labeling delicate proteins and proteins prone to denaturation. Non-sulfonated Cyanine7 NHS ester soluble in the organic phase is also available.
