摘要: 为制备新城疫病毒HN蛋白的单克隆抗体,本研究采用新城疫病毒CK/AH/100/2010作为免疫原,免疫6~8周龄BALB/c小鼠,3次免疫后取脾细胞与SP2/0融合,用血凝抑制(HI)方法检测筛选,具有HI活性的单抗有6株:PX1-PX6。6株单抗与AIV、EDS等其它具有血凝活性的病毒的交叉血凝抑制试验结果表明,6株单抗具有良好的特异性。间接免疫荧光试验结果表明,PX1、PX3可与新城疫病毒CK/GD/263/2010 HN抗原发生特异性反应,而其它单抗不反应。

Abstract: In order to develop monoclonal antibodies of HN protein of Newcastle disease virus, BALB/c mice were immunized with CK/AH/100/2010 virus, and spleens were used for fusion with SP2/0. Six McAb cell strains of PX1 to PX6 were determined by hemagglutinin inhibition (HI). The results of HI cross-reaction with AIV, EDS and other HA virus suggested that the six McAbs had excellent specificity with NDV. The McAbs PX1, PX3 were shown to react with the HN antigen of NDV CK/GD/263/2010 in indirect-immunofluorescence assay.

Key words: Newcastle disease virus; monoclonal antibody; HN gene; HI
