Pierce™ Protein G UltraLink™ and Protein G Plus UltraLink™ resins are useful for purification of antibodies and immunoprecipitation (IP). Samples containing IgG are incubated with the resin-immobilised Protein G in a buffer that facilitates binding. After non-IgG and non-antigen components of the sample are washed from the resin, the bound IgG and antigen may be recovered by elution.

• Immobilised Protein G specifically binds IgG from several mammalian species, especially all isotypes of IgG from human, mouse and rat
• Acrylamide based support provides an alternative to crosslinked beaded agarose supports for medium pressure applications

Protein G UltraLink™ resin binding capacity: >20 mg human IgG/ml resin.

Protein G UltraLink™ column binding capacity: >40 mg human IgG/ml resin.

Protein G Plus UltraLink™ resin binding capacity: >25 mg human IgG/ml resin.
