Product Overview
PMMAC40UM-10 Carboxyl PMMA Microspheres are uniform polymethyl methacrylate microspheres with surface carboxyl (-COOH) functional groups. The carboxyl groups enable efficient covalent coupling with proteins, antibodies, peptides, enzymes and other biomolecules using standard EDC/NHS activation chemistry.
Supplied as a 5% aqueous suspension, these microspheres exhibit excellent particle uniformity, low nonspecific adsorption and outstanding suspension stability. They are widely used in immunodiagnostics, biosensor development, lateral flow assays, molecular biology and life science research.
The highly uniform particle size and stable surface chemistry make PMMAC40UM-10 an excellent choice for assay development and functional biomolecule immobilization.
