Product Overview
PMMAC50UM-10 Carboxyl PMMA Microspheres are monodisperse polymethyl methacrylate microspheres functionalized with surface carboxyl (-COOH) groups. The reactive carboxyl groups allow efficient covalent coupling with proteins, antibodies, enzymes, peptides and other biomolecules using standard EDC/NHS activation chemistry.
Supplied as a 5% aqueous suspension, these microspheres feature excellent particle size uniformity, stable dispersion and low nonspecific adsorption. They are widely used in immunodiagnostics, bioseparation, biosensor development, latex agglutination assays and life science research.
