Description

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 over traditional fluorescent microspheres: • Significantly improve lateral flow assay sensitivity • Drastically reduce background fluorescence • Make assays easier to read and quantify • Exhibit an enhanced fluorescent quantum yield facilitating a low detection limit • Exhibit a much longer Stokes shift than traditional fluorescent labels
