Thermo Scientific™ Pierce™ Protein A IgG Binding Buffer

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.

Finally, the Mouse IgG1 Mild Elution Buffer, when used in combination with Protein A resin, enables selective elution and separation of the IgG1 subclass from total bound mouse IgG.

Highlights:

• Three optimized binding buffers – for Protein A, Protein G or Protein A/G

• Two elution buffer options – acidic (pH 2.8) or high salt (near-neutral)

• Special system for mouse IgG1 – selective, two-stage elution from Protein A agarose
