Pyrene is a polyaromatic hydrocarbon which exhibits fluorescence in blue range of the spectrum. When two pyrene residues are closely spaced, excimer fluorescence is observed at longer wavelength. Therefore, pyrene is useful as a proximity label.

Pyrene exhibits affinity to graphite, and can be used as an anchor group for graphite. This reagent can be conjugated with biomolecules for their subsequent immobilization on graphite surfaces.

This NHS ester allows to label biomolecules with amino groups, such as proteins, peptides, amino-DNA and other molecules.

Pyrene is also a FRET donor for perylene.

芘是一种多环芳烃,在光谱的蓝色范围内显示荧光。 当两个芘残基间隔很近时,在较长波长下观察到准分子荧光。 因此,芘可用作邻近标签。

芘对石墨具有亲和力,可用作石墨的锚定基团。 该试剂可以与生物分子结合,以便随后将其固定在石墨表面上。

这种 NHS 酯允许用氨基标记生物分子,例如蛋白质、肽、氨基 DNA 和其他分子。

芘也是苝的 FRET 供体。
