Abstract
  • We reported previously that TG19318, a synthetic ligand deduced from the screening of combinatorial libraries, displays specific and selective recognition properties for immunoglobulins of the G class and can be used conveniently for affinity chromatography purification of monoclonal and polyclonal antibodies. In this study we have extended the ligand characterization, examining its ability to bind IgA from cell culture supernatants and from IgG-deprived serum. Affinity columns prepared by immobilizing TG19318 on Sepharose allowed convenient one-step purification of monoclonal IgA directly from crude feedstocks, in high yield and with full recovery of immunoreactivity, Optimal column adsorption occurred with phosphate buffer at neutral pH, while elution of adsorbed IgA could be accomplished by a buffer pH change to acidic or basic conditions, Column capacity was close to 7 mg IgA/ml support.
