The present application discloses a luminescent lanthanide chelate comprising one or more chromophoric moieties of the formula (I) or of the formula (III)
wherein R
1
, R
2
and R
2*
each independently are selected from carbon-containing substituents forming a C—O bond with the neighbouring oxygen atom, R
3
and R
4
each represent a bond between the chromophoric moiety and other moieties of the chelate, and Ln
3+
is a lanthanide ion, 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 binding assay utilizing time-resolved fluorometric determination of a specific luminescence, and a solid support material conjugated with the luminescent lanthanide chelate.
本申请公开了一种发光镧系螯合物,包括一个或多个具有以下式(I)或式(III)的色团基团,其中R1、R2和R2*各自独立地选自与相邻氧原子形成C—O键的含碳取代基,R3和R4分别代表色团基团与螯合物的其他基团之间的键,Ln3+是镧系离子,以及相应的发光镧系螯合配体。该申请还公开了一种可检测的分子,包括与发光镧系螯合物结合的生物特异性结合试剂(如抗体),以及进行生物特异性结合测定的方法,利用这种可检测的分子在利用时间分辨荧光确定特定发光的特定生物亲和性结合测定中的应用,以及与发光镧系螯合物结合的固体支持材料。
