When excited with UV light at its maximal absorbance wavelength of 333 nm, europium chelate particles emit long-lived luminescence at 613 nm, with a lifetime of approximately 0.5 milliseconds, which is about 10,000 to 100,000 times longer than the lifetimes of most fluorophores. This extremely long lifetime allows the application of europium particles to time-resolved fluorescence and can reduce the detection limits of fluorescence assays many orders of magnitude by elimination of background interference from relatively short-lived matrix fluorescence.
  • Made by dyeing Thermo Scientific™ OptiLink™ Carboxylate-Modified particles with europium chelate
  • Specifically designed for membrane or automated fluorometric-based applications
  • Available in standard 0.1 μM, 0.2 μM, and 0.3 μM diameters
  • Dyed internally to prevent dye leaching and to assure maximum surface immunoreactivity
