Product Overview

SANYU GROUP CP300-10 Carboxyl Polystyrene Microspheres are monodisperse polymer microspheres with carboxyl (–COOH) functional groups on the particle surface.

CP300-10 has a nominal particle diameter of 300 nm (0.3 μm) and is supplied as a 10% solids aqueous dispersion. The surface carboxyl groups provide active sites for biomolecule immobilization and surface modification.

With stable particle size distribution and reliable dispersion performance, CP300-10 is suitable for antibody conjugation, protein immobilization, immunoassay development, biosensor research and other life science applications.
