摘要
以DHV单克隆抗体包被反应板,以粗提病毒作为抗原,建立了检测DHV抗体的单抗捕捉法ELISA,经与间接ELISA作平行试验,二者检测符合率为100%。
An mAb ELISA for detecting antibodies to duck heptitis virus (DHV)was developed.The test conditions were optimized by reagent titrations utihzing known positive and negative antisera.An appropriate positive/negative(P/N)cutoff level was defined as three times higher than the mean abosorbance of negative sera at a 1∶100 dilution.The results of mAb ELISA for 60 clinical serum samples were correspondence with those of the indirect ELISA.
