Abstract:
The present invention relates to a new class of substituted aza-triangulenium fluorescent dyes having a hydroxy group attached to an aryl as quenching group. The new substituted aza-triangulenium fluorescent dyes may be attached to a linker, conjugated to carrier molecule such as e.g. a protein, a nucleic acid, a lipid, or a saccharide, or deposited or immobilised on solid support materials. The substituted aza-triangulenium fluorescent dyes are useful for various purposes, including use in sensors for monitoring or determining the concentration of analytes, such as H + (pH), Na + , K + , Ca 2+ , O 2 , CO 2 , H 2 O 2 , ionic strength, redox potentials, metal ions,and metabolites.
Abstract:
The present invention relates to a new class of substituted acridinium- and xanthenium-like fluorescent dyes having a 9-x-antracenium rings system. The new substituted fluorescent dyes may be attached to a linker, conjugated to carrier molecule such as e.g. a protein, a nucleic acid, a lipid, or a saccharide, or deposited or immobilised on solid support materials. The substituted fluorescent dyes are useful for various purposes, including use for fluorescence imaging and in sensors for monitoring or determining analytes.
