Product Overview
AMSC1UM-10 Carboxyl Magnetic Silica Beads are silica-coated superparamagnetic microspheres functionalized with surface carboxyl groups for efficient biomolecule immobilization and magnetic separation. The combination of a superparamagnetic core, durable silica shell and reactive carboxyl surface provides excellent coupling efficiency and reliable performance in biotechnology and diagnostic applications.
Supplied as a 5% aqueous suspension, AMSC1UM-10 offers excellent particle size uniformity, rapid magnetic responsiveness and outstanding suspension stability. The surface carboxyl groups can be activated using EDC/NHS coupling chemistry, enabling stable covalent attachment of antibodies, proteins, peptides, enzymes and other amine-containing biomolecules.
