Product Overview
SANYU GROUP Carboxyl Polystyrene Microspheres CP092-10 are high-quality monodisperse polymer microspheres with abundant surface carboxyl (–COOH) functional groups. Manufactured using advanced emulsion polymerization technology, these microspheres provide excellent particle size uniformity, good suspension stability and reliable batch-to-batch consistency.
CP092-10 has a nominal particle diameter of 92 nm (0.092 μm) and is supplied as a 5% solids aqueous suspension. The surface carboxyl groups can be activated using EDC or EDC/NHS chemistry for efficient covalent conjugation of antibodies, proteins, peptides, enzymes, nucleic acids and other biomolecules.
Carboxyl Polystyrene Microspheres are widely used in immunodiagnostics, lateral flow assays, nanoparticle research, biosensors, protein immobilization, molecular biology and life science research.
