Protein G Agarose Resin

HiMedia’s Protein G Agarose Resin consists of rProtein G covalently bound to crosslinked agarose beads and has a very high affinity for IgG (immunoglobulins). Protein G is a genetically engineered recombinant protein which contains three IgG-binding regions of native Protein G. The recombinant Protein G has been covalently immobilized onto 4% cross-linked agarose. Immobilized Protein G is ideal for polyclonal IgG purification from mouse, human, cow, goat and sheep serum, including human IgG3 and mouse IgG1 isotypes. When a suspension (e.g. serum, ascites fluid, tissue culture supernatant) containing mixture of substances along with IgG are loaded on the column, the IgG binds to Protein G and is recovered by elution.
