Pyrenebutyric acid NHS ester

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.
