CAS:2107273-58-3 N-(m-PEG4)-N’-(m-PEG4)-O-(m-PEG4)-O’-(azide-PEG4)-Cy5 is a type of fluorescent dye that is commonly used in biological imaging and detection applications. It is composed of several functional groups, including three methoxy polyethylene glycol (m-PEG4) spacers, an azide-PEG4 group, and a Cy5 fluorescent dye group.
The m-PEG4 spacers in N-(m-PEG4)-N’-(m-PEG4)-O-(m-PEG4)-O’-(azide-PEG4)-Cy5 are used to improve the solubility and stability of the dye in solution, while also helping to reduce any potential toxicity to biological systems. The azide-PEG4 group is a functional group that contains an azide moiety, which can be used for bioorthogonal click chemistry reactions. This allows the dye to be conjugated to other molecules, such as proteins or nucleic acids, for imaging and detection purposes.
The Cy5 fluorescent dye group in N-(m-PEG4)-N’-(m-PEG4)-O-(m-PEG4)-O’-(azide-PEG4)-Cy5 is responsible for the fluorescence of the dye, which makes it useful for imaging applications. The dye emits a red light when excited with a suitable light source, which can be detected using specialized imaging equipment.
