Hi-BindTM Protein G-Agarose beads are specially prepared for high IgG binding by covalently coupling recombinant Protein G to 6% cross-linked Agarose beads, the most popular resin for protein affinity purification methods. BioVision’s Protein G (Cat. # 6510) is a genetically engineered protein containing three IgG-binding regions of native Protein G. The cell wall binding region, albumin binding region and other non-specific regions have been eliminated from the recombinant Protein G to ensure the maximum specific IgG binding. The coupling technique is optimized to give a higher binding capacity for IgG & minimum leaching of recombinant Protein G than the other regular Protein-G Agarose on the market. The IgG binding capacity of Hi-BindTM Protein G-Agarose is ≥ 30 mg of human or rabbit IgG per ml of wet beads. The Hi-BindTM Protein G-Agarose beads are stable in chemical & physical properties with high flow rate, hydrophilicity & high gel strength.
