Protein A UltraLink™ and Protein A Plus UltraLink™ resins are extremely durable beaded polyacrylamide supports to which IgG-binding Protein A has been immobilized for use in IgG purification methods

• Specifically binds IgG from several mammalian species, especially most subtypes of human and rabbit IgG
• Acrylamide-based support provides an alternative to crosslinked beaded agarose supports for medium pressure applications

Protein A resin is used to bind and purify IgG in gravity-flow, spin-column or medium pressure chromatography methods.
