PEP azide,PEP-N3,芘-叠氮荧光染料
目前Cyanine系列染料以两种异构体的形式存在，一种是非磺化花青素（non-sulfonated cyanines），一种是磺化花青素（sulfonatedcyanine）。两者的光谱性质几乎*，因此大部分应用可相互替换。

产品介绍
PEP azide
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-aueous labeling reaction mixtures. With this azide, and Click Chemistry, it is easy to turn any molecule bearing alkyne into PEP-labeled probe.
