MagResyn Carboxyl

For covalent ligand immobilization via primary amine residues

MagReSyn® Carboxyl is a magnetic polymeric microsphere support designed for covalent immobilization of primary amine-containing ligands through carbodiimide-succinimidyl ester activation and subsequent amide bond formation. Various strategies for the activation of carboxylate particles have been documented, but the most commonly used method for coupling proteins and other primary amine-containing ligands is through activation by EDC (1-ethyl-3-(3-dimethylaminopropyl) carbodiimide) in an aqueous reaction. This reaction can be either single-step or a two-step reaction requiring the addition of N-hydroxysuccinimide (NHS) or the more stable sulfo-NHS yielding NHS ester or sulfo NHS ester intermediates.
