摘要

Abstract

The importance of immunoglobulin Y (IgY) as a specific antibody equivalent to mammalian immunoglobulin G (IgG) is well recognized. However

production of highly purified IgY is still difficult due to the lack of specific purification methods. In this study

adsorption behaviors of IgY on four mixed-mode resins with functional ligands of 4-mercatoethyl-pyridine (MEP)

2-mercapto-1-methyli-midazole (MMI)

5-aminobenzi-midazole (ABI) and tryptophan-5-aminobenzi-midazole (W-ABI) were evaluated. The results showed that high adsorption ratio were found at pH 6.0-7.0 with little adsorption under acidic conditions. The resin with ABI ligand was then used to separate IgY from immunized chicken serum. An efficient process with IgY purity of 95% and recovery of 90% was developed after optimization of loading and elution pH and injection volume. The biological activity of the purified IgY was fully maintained. These results indicated that mixed-mode chromatography with specially-designed ligands has great potential for the separation of IgY from crude feedstock.
