    摘要: The present invention provides fluorescent biopolymers that are amino acid polymers conjugated to multiple mono-chlorinated 3-carbonyl-7-hydroxy-coumarin dyes, and methods of their use. The fluorescent biopolymers containing multiple mono-chlorinated 3-carbonyl-7-hydroxy-coumarin dyes generally exhibit superior fluorescence properties compared to biopolymers labeled with multiple non-chlorinated hydroxycoumarin dyes. The fluorescent biopolymers of the invention in which the amino acid polymer is an antigen-specific antibody are particularly useful for analyzing cells by flow cytometers that are equipped with a violet laser as an excitation source due to their strong absorption at 405 nm and high fluorescence quantum yield.

    摘要: 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.
