Product Overview
AMSA2UM-10 Amino Magnetic Silica Beads are high-quality silica-coated superparamagnetic microspheres functionalized with reactive amino groups. The combination of a superparamagnetic magnetic core, chemically stable silica shell and amino-functionalized surface provides an excellent platform for biomolecule immobilization and magnetic separation.
Supplied as a 5% aqueous suspension, AMSA2UM-10 offers excellent particle size uniformity, rapid magnetic responsiveness and stable dispersion. The amino groups can react with aldehydes, activated esters, epoxy groups and commonly used crosslinkers, enabling efficient immobilization of antibodies, proteins, enzymes and other biomolecules for research and diagnostic applications.
