Product Overview
SANYU GROUP Carboxyl Polystyrene Microspheres CP120NM 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.
CP120NM has a nominal particle diameter of 120 nm (0.12 μm). The carboxyl-functionalized surface provides active sites for biomolecule coupling and surface modification.
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. CP120NM is widely used in immunodiagnostics, biosensors, molecular biology and life science research.
