Description

Polystyrene microspheres are are spherical colloidal particles and amorphous polymer. They are synthesized through emulsion polymerization, dispersion polymerization, soap-free emulsion polymerization and other methods. We can provide different particle sizes and surface functional groups, and the number of functional groups can be controlled, which can meet the requirements of customer sensitivity and linear range. Polystyrene microspheres without surface functional groups can combine antigens and antibodies through physical adsorption and can be widely used in enhanced immunoturbidimetry (PET), latex agglutination tests and microsphere capture enzyme-linked immunosorbent assays, etc. In addition, latex microspheres can also be used as templates, measurement standards, additives, etc.

Advantages

  1. Excellent sphericity: Ideal microsphere morphology without any miscellaneous items.
  2. Outstanding repeatability:Small difference between batches.
  3. Superior operability: It can be readily separated by centrifugation.
  4. Highly homogeneous microsphere particle size: CV < 3%.
  5. Easy surface modification: the surface can be attached to different functional groups as required.

    Note

    1. Before extracting the microspheres, they should be thoroughly mixed to prevent alterations in microsphere concentration due to sampling. Any slight sedimentation or agglomeration can be eliminated by ultrasonic treatment; But prolonged ultrasonic exposure should be avoided to safeguard the microsphere surface from damage.
    2. During utilization and storage, freeze-thaw or desiccation should be evaded.
    3. This product is relatively stable under neutral or alkaline conditions. Do not mix polyvalent cations or organic solvents.
    4. The operating temperature should not exceed 100°C to prevent the polystyrene microspheres from melting, deforming, or coalescing.
