    Abstract: The invention describes crown ether chelators, including crown ethers having the formula and aza-substituted and thia-substituted analogs thereof. These crown ethers are substituted by a dye moiety, a chemically reactive group, a conjugated substance, or a combination thereof. Chelators that are substituted by fluorescent dyes are particularly useful as indicators for metal cations, particularly Na+ and K+ ions, and particularly where binding of the target ion results in a change in the fluorescence properties of the indicator that can be correlated with the ion concentration. Methods are provided for utilizing reactive groups on the chelators for conjugation to dyes, lipids and polymers and methods for enhancing entry of the indicators into living cells.

    Abstract: The present invention describes novel dyes, including coumarins, rhodamines, and rhodols that incorporate additional fused aromatic rings. The dyes of the invention absorb at a longer wavelength than structurally similar dyes that do not possess the fused aromatic rings. Many of the dyes of the invention are useful fluorescent dyes. The invention includes chemically reactive dyes, dye-conjugates, and the use of such dyes in staining samples and detecting ligands or other analytes.

    Abstract: Chemically-reactive, water-soluble, heterocycle-substituted 7-hydroxycoumarin dyes, their bioconjugates and uses are described. The conjugates derived from reactive heterocycle-substituted 7-hydroxycoumarin dyes are used for analyzing biological compounds. These heterocycle-substituted 7-hydroxycoumarin dyes are particularly useful as fluorescent labels for biopolymer detection reagents, such as antibodies or nucleic acid probes. The dye-antibody conjugates of the invention are particularly useful for analyzing analytes using a flow cytometer equipped with a violet laser as an excitation source due to their strong absorption at 405 nm and high fluorescence quantum yield.
