About
Polysciences’ Europium Chelate Carboxylate Microspheres are monodisperse polystyrene beads (0.10 µm, 0.20 µm, 0.30 µm) supplied as ~1% aqueous suspensions, offering extremely bright fluorescence (excitation max ~365 nm, emission max ~610 nm) combined with well-functionalized carboxylated surfaces for covalent ligand attachment. These beads are ideal for assay development in immunochromatographic formats, microwell plates, and other diagnostic applications that require low background and high signal stability.
