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. The Protein A IgG Binding Buffer is a phosphate-based buffer containing glycerol and EDTA, formulated for antibody purification using Protein A.
Shared features of all Thermo Scientific Pierce IgG Binding and Elution Buffers:
• 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
