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.

Phenylethynylpyrene (PEP) 荧光团是一种对微环境具有高度敏感性的多环芳烃标记物。 与芘类似,PEP 染料很容易形成准分子。 然而,PEP 荧光更红移

PEP 可用作微环境探针,并用作基于准分子形成的分析的标记。

该试剂含有三甘醇接头,以促进非极性 PEP 染料在有机水标记反应混合物中的溶解。 使用这种叠氮化物和 Click Chemistry,很容易将任何带有炔烃的分子转化为 PEP 标记的探针。
