How was my AbD Serotec polyclonal antibody purified?
Many AbD Serotec polyclonal antibodies are purified using antigen-affinity chromatography. This results in an antibody preparation of at least 90% antigen specific antibody, providing high titers and minimal cross-reactivity with other proteins. Some polyclonal antibodies are purified using Protein A or Protein G chromatography, ion exchange chromatography, or by ammonium sulfate precipitation. In these cases the total IgG content is usually >90%, however due to the nature of polyclonal antibodies, it is likely that the specific antibody content will be approximately 10%.
