Product Overview
AMSC20UM-10 Carboxyl Magnetic Silica Beads are high-quality silica-coated superparamagnetic microspheres functionalized with reactive carboxyl groups. Combining a superparamagnetic core, chemically stable silica shell and carboxyl-functionalized surface, these beads provide excellent performance for covalent biomolecule immobilization and magnetic separation.
Supplied as a 5% aqueous suspension, AMSC20UM-10 features uniform particle size, rapid magnetic responsiveness and excellent suspension stability. The surface carboxyl groups are readily activated using EDC/NHS coupling chemistry, allowing efficient covalent attachment of antibodies, proteins, peptides, enzymes and other amine-containing biomolecules.
