中文摘要：

为检测I型IBDVVP2蛋白线性B细胞抗原表位肽PJl4和PJ5的免疫原性，将人工合成并纯化的PJ14和PJ5分别与牛血清白蛋白（BSA）和卵清白蛋白（OVA）偶联；将与BSA偶联的PJ14和PJ5分别免疫BALB／c小鼠，然后以与OVA偶联的PJ14和PJ5作为间接酶联免疫吸附试验抗原，分别测定免疫鼠血清中抗相应多肽的抗体。结果显示，免疫小鼠产生了抗PJ14和PJ5的抗体，抗体持续期达21周。表明PJ14和PJ5具有免疫原性。

英文摘要：

The peptides of the linear B-cell epitopes PJ14 and PJ5 on the VP2 protein of infectious bursal disease virus（IBDV） were synthesized and purified, then were conjugated to carrier protein BSA or OVA respectively. The BSA-conjugated PJ14 and PJ5 were inoculated into the BALB/c mice respectively. The OVA-conjugated PJ14 was used as the antigen to detect the anti-PJ14 antibody in the serum of the immunized mice,and so was the OVA-conju- gated PJS. The results showed that the PJ14 and PJ5 after the conjugation to BSA stimulated the production of the an- ti-PJ14 and anti-PJ5 antibody respectively, and that the antibodies lasted for twenty-one weeks. It indicated the immu- nogenicity of the PJ14 and PJS.
