For the Capture and Purification of
Monoclonal and Polyclonal Antibodies

• High purity in a single step - Product purities of 70% to 90% or greater are typically achieved
• Rapid sample processing - Dynamic binding capacities of > 30 mg IgG per mL of sorbent (at 10% breakthrough) are routinely achieved
• Exhibits high IgG capacity, independent of sub-class or species
• Allows direct sample loading without adjustment of pH or ionic strength
• Effective capture, even with feedstocks as dilute as 50 to 100 μg IgG/mL
• Offers easy cleaning with sodium hydroxide

• Capture and purification of antibodies from a broad range of sources such as animal sera, ascites fluid, and cell culture supernatant.
• Independent of subclass or species.Weakly-binding variants (e.g., murine IgG, rat IgG) are well retained.
• Alternative to traditional HIC sorbents for capture of hydrophobic molecules.
• Has been studied in a broad range of applications including isolation of antibodies from sweet-whey and colostrum; isolation of antibodies from transgenic plant and animal sources; and, isolation of IgA and selected fusion proteins

Monoclonal Antibodies Purification on MEP
HyperCel Resin from Cell Culture Supernatants

Sample A = 300 mL protein-free cell culture supernatant.Sample B = 300 mL cell culture supernatant containing 5% fetal bovine serum; Equilibration:50 mM Tris-HCI, pH 8; Elution:50 mM acetate, pH4; Flow rate:70 cm/h.In curve B, (a) and (b) are respectively water and 25 mM sodium caprylate washings; SDS-PAGE (reduced conditions):(1) = crude sample; (2) = purified IgG; (H) = heavy chain; (L) = light chain.
