间接ELISA法检测鸡新城疫抗体
CHINESE JOURNAL OF VETERINARY DRUG（2005）
Abstract
应用醛化的鸡红细胞经吸附释放方法获得纯化的新城疫病毒(NDV),经triton X-100处理并反复冻融制备新城疫 ELISA抗原.应用抗鸡Ig轻链单抗1B7辣根过氧化物酶结合物建立了定量检测NDV抗体水平的ELISA方法.确立了将鸡血清100倍稀释检测ELISA效价(ET)的回归方程y=0.941 28 x+0.206 77,r=0.981 63,可用于定量测定.血凝抑制(HI)方法与ELISA方法的比较试验表明,ELISA法的敏感性是HI方法的3倍以上.应用建立的ELISA方法比较了卵黄、气管及胆汁中局部抗体与血清抗体的差异.
