摘要
采用鸡传染性法氏囊病(IBD)病毒(IBDV-2512)研制了检测IBOV抗体的ELISA试剂盒。抗原最佳包被浓度为5.12μg/ml,被检血清最佳稀释度为1:200,酶标结合物最佳工作浓度1:1000.本试剂盒与美国KPIIBD-ELISA试剂盒比较,结果敏感性、特异性、重复性均达到美国同类产品水平,且易于操作.在4℃可稳定保存6个月、对北京地区4个非免疫鸡群的103只鸡测得其阳性率为54%,对45只SPF鸡的阳性率为0%。
Abstract ELISA kit for detecting antibody against infectious Bursal Disease (IBD) was developed with IBDV-2512 strain. The optimum Concentration of COated antigen was 5. 12ug/ml, the optimum serum titer was l: 200 and the optimum conjugate titer was 1 1 1000. The ELISA kit was specific, Sensitive, reprodllcible and easy' to'Perform. The results showed as good as that of the ELISA kit KPL ABORATORIES made in USA. It Can be stored at 4C for six months. The resultS of serological monitoring using the ELISA kit revealed that the posihve rate of antibody was 54 % and 0 % in Conventional and SPP chickens.
