Thermo Scientific Pierce IgG Binding and Elution Buffers ensure high-yield, nondenaturing antibody purification with IgG affinity purification supports, such as Protein A and Protein G agarose beads.

These products include IgG Binding Buffers specific for each immunoglobulin-binding protein （Protein A, Protein G, Protein A/G）. The Pierce IgG Elution Buffer provides efficient dissociation and elution of antibodies from all three IgG-binding proteins, including Protein L. This low-pH elution buffer is also effective for most antibody-antigen or protein-protein affinity purification systems.

The Gentle Ag/Ab Binding and Elution Buffer system uses near-neutral, high-salt conditions for elution, enabling even sensitive and labile antibodies （or other proteins） to be eluted from an affinity system without denaturation and inactivation. The phosphate-free binding buffer in this system is a necessary substitute for the Protein A binding buffer （pH 8）, which precipitates with the Gentle Ag/Ab Elution Buffer.

Highlights:

• Ready to use – carefully formulated and prefiltered 1X solutions
• Three binding buffers – optimized for Protein A, Protein G or Protein A/G
• Two elution buffer options – acidic （pH 2.8） or high salt （near-neutral）
• Versatile – elution buffers are appropriate for antibody-antigen affinity purification
