Abstrakt: In order to develop new markers for immunofluorescence time-resolved luminescence analysis tetraketodiester carbazole series was obtained. Compound contains methoxycarbonyl reactive groups, separated from the 1,3-dicarbonyl chelating fragment by difluoromethylene spacers (CF2)4. Complexes of this compound with the ions Eu3+ are stable in aqueous solution and possess a long-living intensive luminescence with the main peaks: emission--in the area of 615 nm and excitation--in the 380-390 nm, that distinguishes them from most used analogues. Conjugate of streptavidin to compound was obtained and its fluorescent spectral characteristics allow to use it as a universal reagent for various schemes of biological microanalysis.
