摘 要：利用60Coγ射线照射卵黄抗体，分析了60Coγ射线对IgY的效价、纯度、热稳定性、耐酸性以及酶水解试验等理化特性的影响和不同温度下的保存时间。结果表明照射达10kGy时，对IgY的效价和纯度无影响；对照组和照射组热稳定性、耐酸性无差异，但照射组更易被酶水解；照射后的IgY明显延长了保存期。

Abstract: The Immunized Egg Yolk was irradiated by 60Coγ ray, and then we investigated the effect of 60Co γ ray on antibody titer、purity、heat stability、acid resistance、enzymatic hydrolysis and other activity and physic-chemistry characters of it. When irradiation was up to 10kGy， the results showed that there was no effect on antibody titer and purity of IgY；there was no differece in heat stability and acid resistance beween the irradiated group and the control group，but the irradiated group was more easily hydrolyzed by enzyme；The retention period of irradiated IgY was obviously prolonged.
