| Abstract: | The objective of the study is to obtain highly purified chicken IG and maintain its biological activity.Some methods about purification of serum IgG from chicken were appraised.Firstly,chicken serum was extracted by saturated ammonium sulfate precipitation or ethanol precipitation.After dialysis for desalination,the original extracts are purified by sephadex G-200 column chromatography.The purified chicken IgG was identified by SDS-PAGE.The study has found a fairly good method in obtaining purified chicken serum IgG and provided the basis for further experiment. |
