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.

Coumarin 343 X azide
Coumarin 343 is a blue emitting fluorophore that can serve as a FRET donor for fluorescein (FAM). This azide derivative can be conjugated with alkynes by Click chemistry. An extended linker arm between the fluorophore and the azide group enhances solubility, and provides spatial separation between the dye and the biomolecule.DBCO NHS ester
Azodibenzocyclooctyne (DBCO, ADIBO) reagent for strain promoted copper free Click chemistry (spAAC). The reagent contains an NHS ester function for the attachment of the cyclooctyne to various molecules.General properties
