Phenylethynylpyrene (PEP) fluorophore is a polyaromatic hydrocarbon label with high sensitivity to microenvironment. Similarly to pyrene, PEP dye readily forms excimers. However, PEP fluorescence is more red-shifted PEP can be used as microenvironment probe, and as a label for assays based on excimer formation. This reagent contains triethyleneglycol linker to facilitate dissolution of non-polar PEP dye in organo-aqueous labeling reaction mixtures. With this azide, and Click Chemistry, it is easy to turn any molecule bearing alkyne into PEP-labeled probe.
