Definitions

  • temporal discrimination time-resolution
  • organic donor-acceptor pairs of different decay times using pyrene as the long excited state donor, pulsed laser for excitation and phycoerythrin as the short decay-time acceptor (US 4,822,733).
  • time-resolved energy transfer principle is applied for homogeneous solution hybridization using fluorescein (Morrison et al (1989) Illrd International Symposium on Quantitative Luminescence Spectrometry in Biomedical Sciences, Ghent Belgium) as acceptor.
  • a particularly preferred group of long excited state lifetime lanthanide chelates are Compounds 1 to 12 the structure of which is dislosed in Scheme 1 to 5.
  • ⁇ exc means excitation wavelength, ⁇ decay time and G x ⁇ luminescence yield.
  • the values given in the schemes are measured from the compound coupled to a protein. 98/15830
  • covalently conjugated probes e.g. those of xanthene dyes (rhodamine, tetramethylrhodamine, Texas
  • the great number of acceptor molecules may compensate the long distance after bead coating, and the luminescent bead actually provide a energy accepting surface.
  • the bead can absorb most of the donor emitted light, a simple radiative enery transfer can be applied, in which the energy transfer is a function of space angle and critical distance with 10 ⁇ m beads is in the range of micrometers.
  • the binding proteins e.g. agglutinin

Abstract

L'invention concerne des améliorations des analyses homogènes basées sur le transfert d'énergie, qui utilisent la fluorimétrie à résolution temporelle en détection. Les améliorations spécifiques concernent le type de marqueurs à base de chélates de lanthanides utilisés comme donneurs d'énergie, des accepteurs d'énergie optimisés pour des analyses définies, la façon dont le transfert d'énergie est mesuré au moyen de filtres et de fenêtres temporelles optimisés, les manières de corriger toutes les interférences possibles liées aux échantillons, l'utilisation de l'analyse pour une analyse à plusieurs composantes et la mise au point de protocoles d'analyse simplifiés.
