利用灭活的猪血凝性脑脊髓炎病毒加弗氏完全佐剂和弗氏不完全佐剂免疫家兔,制备高免血清,浈q定其效价;用硫酸铵-蛋白A亲和层析法分离纯化兔血清IgG,并采用SDS—PAGE和EUSA对IgG纯化产物进行检测。结果表明,兔抗HEV高免血清的效价为1:12800;采血并分离血清,经过亲和层析纯化得到的兔抗HEVIgG,效价达1:50000。
利用滅活的豬血凝性腦脊髓炎病毒加弗氏完全佐劑和弗氏不完全佐劑免疫傢兔,製備高免血清,湞q定其效價;用硫痠銨-蛋白A親和層析法分離純化兔血清IgG,併採用SDS—PAGE和EUSA對IgG純化產物進行檢測。結果錶明,兔抗HEV高免血清的效價為1:12800;採血併分離血清,經過親和層析純化得到的兔抗HEVIgG,效價達1:50000。

In this study, hyperimnmne serum was prepared to inactivale porcine hemagglutinating encephalomyelitis virus with Freund's complete adjuvant and Freund' s incomplete adjuvant in rabbits; then rabbit serum IgG was purified by ammonium sulfateprotein A affinity chromatography. The effct of purified lgG was tested by SDS-PAGE and ELISA. The results showed that the titer of rabbit hyperimmune serum anti-HEV was 1:12 800; the titer of IgG anti-HEV was 1:50 000.
