Project Description
Our functionalized polystyrene latex microspheres including carboxyl, amine, epoxy, aldehyde, methyl groups are suitable for the covalent immobilization of polypeptide, protein, antibody, oligonucleotides and other biomolecules. Microspheres with particle size below 3um are supplied as a 10% solids suspension (100mg/mL) in de-ionized water with surfactant and sodium azide. Microspheres with particle size larger than 3um are usually supplied in powder form but can also be supplied in dispersion form according to customers’ requirement.
Amine Polystyrene Beads
Amine-functionalized microspheres offer further options for coupling of biomolecules. Glutaraldehyde is commonly used for the immobilization of amine-containing compounds, and specialized linkers are available for targeted coupling of thiol or carbohydrate moieties.

Carboxyl Polystyrene Beads
Our carboxylate-modified polystyrene latex microspheres are suitable for the covalent immobilization of proteins, peptides, nucleic acids, turbidimetric assay, flow cytometric immunoassay, and homogenous immunoassay. EDAC-mediated coupling is often used for the covalent immobilization of amine-terminated proteins, DNA, or other molecules on carboxyl-functionalized PS and PS/DVB microspheres.
