PMMAC10UM-10 10μm Carboxyl PMMA Microspheres for Protein and Antibody Coupling

Product Overview

PMMAC10UM-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 PMMAC10UM-10 an excellent choice for assay development and functional biomolecule immobilization.

Frequently Asked Questions

What are Carboxyl PMMA Microspheres?

Carboxyl PMMA Microspheres are PMMA microspheres functionalized with surface carboxyl (-COOH) groups for covalent attachment of proteins, antibodies and other biomolecules.

How are proteins coupled to PMMAC10UM-10?

Proteins and antibodies are typically coupled using EDC/NHS activation chemistry, which activates the carboxyl groups to form stable covalent amide bonds with primary amines.

What applications are PMMAC10UM-10 suitable for?

They are widely used in immunodiagnostics, lateral flow assays, latex agglutination tests, biosensors, molecular biology and biomedical research.

Can PMMAC10UM-10 be customized?

Yes. SANYU GROUP offers customization of particle size, carboxyl density, solid content, buffer system, packaging and OEM production.
