Lumiprobe PEP azide熒光染料

Lumiprobe PEP azide熒光染料

Phenylethynylpyrene(PEP)熒光素屬于多環芳烴類標記物,有較高靈敏度,是對微環境進行標記的試劑。類似于Pyrene,PEP dye很容易形成激發物。然而,PEP熒光多為紅移。PEP可以用作微環境探針,基于激發態標記實驗。

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.
