    Abstract: The quenching compounds of the invention are nitrogen-substituted xanthenes that are substituted by one or more aromatic or heteroaromatic quenching moieties. The quenching compounds of the invention exhibit little or no observable fluorescence and efficiently quench a broad spectrum of luminescent compounds. The chemically reactive quenching compounds possess utility for labeling a wide variety of substances, including biomolecules. These labeled substances are highly useful for a variety of energy-transfer assays and applications.

    Abstract: The invention relates to nucleic acid stains that are homo- or heterodimers of unsymmetrical cyanine dyes, where at least one dye unit of the dimer is a substituted or unsubstituted benzazolium- or naphthazolium-pyridinium derivative, which dye unit is linked to another unsymmetrical cyanine dye unit, that is the same or different by an aliphatic chain containing one or more heteroatoms; such that the fluorescence of the dye molecules, when bound to nucleic acids, is enhanced. These dimers of unsymmetrical cyanine dyes have spectral properties and binding affinities superior to related monomers. In addition, the dyes can be tailored to absorb and emit in a wide range of wavelengths, which can be further varied by energy transfer mixtures, making the dyes useful for applications that involve simultaneous use of multiple dyes.
