Fluorescent Carboxylate PS Microspheres

Polysciences’ Fluorescent Carboxylate PS Microspheres collection features monodisperse polystyrene beads internally dyed and surface-modified with carboxylate groups, enabling efficient covalent biomolecule coupling and high-signal fluorescence for advanced life-science workflows. Available in a wide range of diameters (e.g., 0.30 µm, 1.00 µm, 10.0 µm) and packaged as 2.5 % aqueous suspensions, these beads support applications such as cell tracking, immunoassays, flow cytometry calibration, and microsphere-based diagnostics.
