Product Overview
AMSA200-10 Amino Magnetic Silica Beads are silica-coated superparamagnetic nanoparticles functionalized with reactive amino groups. Combining a highly responsive magnetic core, chemically stable silica shell and amino-functionalized surface, these beads provide an excellent platform for biomolecule immobilization and magnetic separation.
Supplied as a 5% aqueous suspension, AMSA200-10 offers excellent particle size uniformity, rapid magnetic responsiveness and stable dispersion. The amino-functionalized surface readily reacts with aldehydes, activated esters, epoxy groups and other reactive molecules, making these beads suitable for antibody immobilization, protein conjugation and molecular diagnostics.
