摘要
本文报道一种新的制备和纯化HCG的方法.人工流产物经45%乙醇抽提、调pH5.2~5.4后40~60%乙醇分级、植物血球凝集素-Sepharose4B柱层析纯化后,低温酒精沉淀干燥,可得到比效价3777.8IU/mg的hCG精品.
In this paper is reported a new method for preparation and purification of human chorionic gonadotropin (HCG) from artificial abortion. Crude HCG was purified by 45 % alcohol extraction, then by 40~60 % alcohol fractionation at pH5. 2~ 5. 4, and then by the phytohemagglutinin (PHA ) sepharose 4B affinity chromatography and the precipitation of affinity eluant by alcohol at low temperature to obtain refined HCG whose immunizing potency is 3777. 8 IU/mg.
