Product Overview
AMSC500-10 Carboxyl Magnetic Silica Beads are silica-coated superparamagnetic nanoparticles functionalized with surface carboxyl groups for reliable biomolecule immobilization and magnetic separation. The combination of a superparamagnetic core, chemically stable silica shell and reactive carboxyl surface provides excellent performance in immunodiagnostics and life science research.
Supplied as a 5% aqueous suspension, AMSC500-10 offers excellent particle size uniformity, rapid magnetic responsiveness and stable dispersion. Surface carboxyl groups can be activated through EDC/NHS chemistry to covalently immobilize antibodies, proteins, peptides, enzymes and other amine-containing biomolecules.
