General description
Estapor® microspheres have been the top choice for many lateral flow diagnostic test manufacturers. Used in millions of assays made by internationally known brands, our microspheres are adapted to both qualitative and quantitative Lateral Flow Immunoassays.
Application
Main applications of the fluorescent microspheres include qualitative and quantitive Laterflow ImmunoAssays (LFIA)
Features and Benefits
Europium microspheres provide several advantages overtraditional fluorescent microspheres:Significantly improve lateral flowassay sensitivity.Drastically reduce backgroundfluorescence.Make assays easier to read andquantify.Exhibit an enhanced fluorescentquantum yield facilitating a low detection limit.Exhibit a much longer Stokes shiftthan traditional fluorescent labels.
