Phagocytosis and Cell Uptake Research
The particles may be evaluated as model polymer particles in phagocytosis, particle uptake and cell-interaction studies.
Why Choose 500nm Polystyrene Microspheres?
The 500 nm diameter provides a practical balance between submicron particle behavior and strong optical detectability.
Its spherical morphology supports consistent comparative testing in analytical, biological and materials research.
Typical applications include:
Particle characterization
Protein adsorption
Latex agglutination
Turbidimetric assays
Optical scattering
Particle counting
Membrane evaluation
Microscopy imaging
Standard Plain Polystyrene Surface
SPS500-10 has a non-functionalized polystyrene surface without added carboxyl or amino groups.
The plain hydrophobic surface is suitable for general particle research and passive biomolecule adsorption.
For controlled covalent coupling, SHBC also supplies carboxyl, amino and other functionalized polystyrene microspheres.
Benefits of 5% Solid Content
SPS500-10 is supplied at 5% solids for flexible laboratory and production use.
The concentrated format allows users to prepare different working concentrations while reducing packaging volume and supporting repeated testing, formulation development and bulk projects.
Standard Microspheres or Certified Size Standards?
SPS500-10 is positioned as a standard plain polystyrene microsphere for research and method development.
It should only be described as a certified or traceable particle-size standard when corresponding certification documents are supplied for the specific product and batch.
Customers requiring calibration materials should confirm particle-size tolerance, CV, testing method and traceability requirements before ordering.
