Product Overview
SANYU GROUP Carboxyl Polystyrene Microspheres CP200NM-10 are high-quality monodisperse polymer microspheres with surface carboxyl (–COOH) functional groups. Manufactured using advanced emulsion polymerization technology, these microspheres provide excellent particle size uniformity, stable dispersion performance and reliable batch-to-batch consistency.
CP200NM-10 has a nominal particle diameter of 200 nm (0.2 μm) and is supplied as a 10% solids aqueous suspension. The surface carboxyl groups provide active sites for biomolecule immobilization and surface modification.
The 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. CP200NM-10 is widely used in immunodiagnostics, biosensors, molecular biology and life science research.
