Fluoro-Max Fluorescent Streptavidin-Coated Particles

Catalog number: 29470701011150
Simplify the binding process with a universal binding reagent by using Thermo Scientific™ Fluoro-Max Fluorescent Streptavidin-Coated Particles in a variety of applications such as clinical diagnostics, immuno/histological studies and research. With an extremely broad Stokes shift, europium chelate particles help prevent nonspecific fluorescence interference. They are also excellent for quantitative membrane-based rapid assays, heterogeneous assays, luminescent assays, research applications, phagocytosis studies, cell surface markers and pore size determination.

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
