    摘要: The present invention provides a method for preparing an antitumor biological product, in which after having a chicken embryo vaccinated with Newcastle disease virus (NDV), the allantoic fluid is collected therefrom, subjected to ultrafiltration, concentrated and then purified, and finally a cleavage treatment is carried out thereto so as to obtain the product. By way of this method for preparing the antitumor biological product, the hemagglutination titer of the virus fluid is significantly improved, the purity of the NDV greatly increased, hybrid proteins such as ovalbumin in the virus decreased, the side effects of virus to a human body reduced, and the antitumor effects of the NDV virus enhanced, therefore it has very important application and economic values.
