摘要
Abstract
In order to develop an indirect ELISA for the detection of antibodies against IBDV, VP2 gene(1nt~708nt) was amplified by RT-PCR and expressed using the pET-28a vector inEscherichia coli BL21. The recombinant protein was purified through Ni-chelating affinity chromatography and based on it,an indirect ELISA was developed. To verify the performance of this assay, 156 clinical serum samples were detected by the assay and IDEXX ELISA kit in paral-lel. The results showed that VP2 gene was successfully amplified by RT-PCR and expressed inE.coli BL21 with IPTG induction. Compared to IDEXX ELISA kit, the specificity,sensitivity,and coincidence rate of the developed indirect ELISA were 90.24%,95.65% and 94.23% respectively.The results demonstrated the assay was sensitive and spe-cific,and could be used to detect antibodies against IBDV in chicken sera.关键词
