摘要
应用鸡抗EDS-76病毒、兔抗EDS-76病毒抗体和羊抗兔抗体,建立了检测EDS-76的双夹心ELISA方法,本试验确定的鸡抗EDS-76病毒抗体、兔抗EDS-76病毒抗体和HRP-羊抗兔抗体的最佳工作浓度分别为1∶160、1∶300和1∶1000。本法对纯化EDS-76病毒的最低检出量约为5 ng/孔。通过对EDS-76病毒试验感染鸡脏器带毒、排毒情况和临床样本的检测,表明双夹心ELISA方法对EDS-76病毒的检测特异性强、敏感度高、适合于成批样本的检测。
A double sandwich enzyme linked immunosorbent assay (ELISA) was developed for the detection of egg drop syndrome-76 (EDS-76) by employing chicken anti-EDS-76 virus, rabbit anti-EDS-76 virus and sheep anti-rabbit serum. The optimal dilutions of chicken anti-EDS-76 virus, rabbit anti-EDS-76 virus and HRP-sheep anti-rabbit were 1 : 160, 1 : 300 and 1:1000, respectively. The result showed that it could detect minimal to 5 ng/well of the purified EDS-76 virus antigen. The detection to the sample from experimental infected chickens and the clinical cases showed that the method of double sandwich ELISA has high sensitivity, good specify, and is suitable to test large numbers of samples.
