Product Overview
AMSC3UM-10 Carboxyl Magnetic Silica Beads are silica-coated superparamagnetic microspheres functionalized with surface carboxyl groups for efficient covalent biomolecule immobilization and magnetic separation. The combination of a highly responsive magnetic core, chemically stable silica shell and reactive carboxyl surface provides reliable performance for biotechnology, diagnostics and laboratory research.
Supplied as a 5% aqueous suspension, AMSC3UM-10 offers excellent particle size uniformity, rapid magnetic responsiveness and outstanding suspension stability. Surface carboxyl groups can be activated using EDC/NHS coupling chemistry, allowing stable covalent attachment of antibodies, proteins, peptides, enzymes and other amine-containing biomolecules.
