rProtein A Agarose 4FF, Prepacked Cartridge

• Cat#No#: AC-018A
• Common Name: Protein A
• Product Overview: rProtein A Agarose 4 Fast Flow is an affinity chromatography medium designed for easy, one-step purification of immunoglobulins, notably IgG isotypes, as well as Fc region-containing fusion proteins.
  Protein A, a bacterial cell wall protein isolated from Staphylococcus aureus, binds to the Fc region of most immunoglobulins through interactions with the heavy chain. Native Protein A contains five high affinity IgG binding domains and many other domains with unknown functions. The recombinant Protein A coupled to the agarose resin is produced in E. coli and contains five high affinity IgG binding domains with other non-essential domains removed to reduce nonspecific binding. Essentially the same as the native Protein A, rProtein A is capable of binding with high affinity to the Fc region from IgG of several species including human and rabbit.
  
  Enabled by proprietary ProteIndex™ technology, immobilization of recombinant Protein A on 4% highly cross-linked agarose resins was very stable and was optimized for high yield in laboratory preparations and scale-up applications.
