    摘要: The present invention aims to provide a novel compound for measuring cellular cytotoxicity or cell proliferation capacity accurately with high reproducibility, conveniently and rapidly, and a measurement method of cellular cytotoxicity or cell proliferation capacity by using the compound. The present invention relates to a compound represented by the formula (I): wherein R1 is a substituent, R2 and R3 are each an optionally substituted hydrocarbon group, or an optionally substituted heterocyclic group, Y is a substituent, n is an integer of 0-3, Z is a single bond, —O—, —S—, —SO—, —SO2—, or —NR4— (R4 is a hydrogen atom or a substituent), and A is an optionally substituted C1-6 alkylene group) or a salt thereof.

    摘要: The present application discloses a luminescent lanthanide chelate of formula (I) with lanthanides such as europium, as well as the corresponding luminescence lanthanide chelating ligand. The application also discloses a detectable molecule comprising a biospecific binding reactant (such as an antibody) conjugated to the luminescent lanthanide chelate as well as a method of carrying out a biospecific binding assay, the use of such a detectable molecule in a specific bioaffinity based assay, the use of such a detectable molecule in a specific bioaffinity based binding assay utilizing time-resolved fluorometric determination of a specific luminescence, and a solid support material conjugated with the luminescent lanthanide chelate.
