Polystyrene Particles

Polystyrene Particles are high-purity, monodisperse polymer microspheres widely used in biotechnology, molecular diagnostics, immunoassays, and flow cytometry calibration. These polystyrene microspheres offer excellent size uniformity, optical clarity, and surface stability, making them ideal for cell separation, particle-based detection, and nanoparticle research. Available in a range of diameters from nanometers to micrometers, functionalized polystyrene beads can be modified with carboxyl (–COOH), amine (–NH₂), or streptavidin groups for easy conjugation with antibodies, proteins, or nucleic acids. Their consistent performance and chemical versatility make latex polystyrene particles essential for ELISA bead assays, diagnostic reagent development, calibration standards, and bioassay optimization. Each batch of polystyrene spheres is manufactured under strict quality control, ensuring reproducibility, traceability, and compatibility with modern analytical and life science platforms.
