Fluorescein (FAM) is one of the oldest yet well known fluorescent dyes. This derivative of FAM contains cyclooctyne group (dibenzocyclooctyne, abbreviated as DBCO or ADIBO) for the conjugation with azides via copper-free, strain-promoted azide alkyne cycloaddition (spAAc).
FAM DBCO can be used for the labeling of proteins, peptides, nucleic acids, and other molecules containing azide groups. Azides react with DBCO spontaneously upon simple mixing. The reaction does not require any catalysts, and it is very efficient.
Fluorescein can be detected using a variety of different instruments.

Water-soluble Cyanine 5 succinimide ester.Coumarin 343 X NHS ester
Coumarin 343 is a blue emitting dye that can serve as a FRET donor for fluorescein (FAM). This structure features a linker between Coumarin 343 fluorophore, and the functional group. It provides better solubility, and spatial separation between the dye, and the functional group.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
