Applications in Immunoassay Research
PS20-10 Polystyrene Microspheres can be evaluated for:
Antibody adsorption studies
Antigen immobilization research
Protein–particle interaction analysis
Immunoassay carrier development
Nanoparticle-based assay optimization
Blocking buffer evaluation
Non-specific adsorption studies
Diagnostic reagent raw material research
Colloidal formulation development
Protein loading, biological activity and storage stability should be optimized according to the selected antibody, antigen, buffer and blocking system.
Protein Adsorption and Surface Development
The hydrophobic polystyrene surface can support passive adsorption of proteins and other biological ligands.
No chemical activation reagent is normally required for initial adsorption screening. Researchers can optimize coating performance by adjusting:
Protein concentration
Buffer pH
Ionic strength
Coating time
Mixing conditions
Blocking reagent
Storage formulation
For applications requiring controlled covalent coupling, SHBC can also provide polystyrene microspheres with customized functional groups.
