The base matrix is activated through a long hydrophilic spacer arm with N-hydroxysuccinimide at the end that is particularly helpful in the immobilization of structurally restricted ligands such as proteins and peptides. It reacts directly with the primary amine groups in molecules to be immobilized to form stable amide bond.

NHS (N-hydroxysuccinimide)-activated SepFast MAG is used to make magnetic adsorbents coupled with molecules containing amine groups. Coupling biospecific ligands to NHS-activated agarose is a successful and well-documented technique. The coupling reaction is spontaneous, rapid and easy to carry out. No toxic chemicals or special equipment is required.

Agarose has long been used for chromatographic separations due to its excellent hydrophilic and low non-specific-binding nature. The particles have an open pore structure with excellent mass transfer propertie to various molecules.

NHS activated SepFast MAG 4HF is made of highly cross-linked 4% agarose containing magnetic material. It shows high mechanical rigidity and allows harsher operational conditions.

This pre-activated resin can be readily employed to make various magnetic affinity chromatography adsorbents for a variety of purification applications. After binding of target molecules, the magnetic resin can be readily isolated from the biological feedstocks with the aid of a magnet.
