GeloPure Phenyl resin is a chromatography media, can remove aggregates efficiently from antibodies, synthesized by standard polysaccharide ligand modification technology. After affinity chromatography like protein A, protein L or protein G, the antibody samples are passed through GeloPure Phenyl chromatography, the aggregates are bound to the hydrophobic ligand of the chromatography media and antibody monomers are coming out in flowthrough fraction. GeloPure Phenyl can be used as flow-through purification mode that selectively bounds such as aggregates or polymers.
