Product Overview
AMSC200-10 Carboxyl Magnetic Silica Beads are high-quality silica-coated superparamagnetic nanoparticles functionalized with surface carboxyl groups. The combination of a superparamagnetic core, chemically stable silica shell and reactive carboxyl surface provides an excellent platform for covalent biomolecule immobilization and magnetic separation.
Supplied as a 5% aqueous suspension, AMSC200-10 exhibits excellent particle size uniformity, rapid magnetic response and outstanding dispersion stability. The carboxyl groups readily react with primary amines through EDC/NHS coupling chemistry, enabling efficient immobilization of antibodies, proteins, peptides and enzymes for life science and diagnostic applications.
