摘要
目的:探讨禽流感病毒单克隆抗体的生物学特性。方法:制备H5N1禽流感病毒的单克隆抗体,鉴定其亚型、效价、血凝抑制活性以及与其他亚型流感病毒的交叉反应性。免疫印迹方法验证单抗与H5N1抗原的结合,人体正常组织芯片的免疫组织化学染色法观察单抗的组织学反应。结果:发现两株禽流感病毒H5N1的单抗(H5-32和H5-35)分别与人体的肾、胰腺组织存在阳性结合。结论:禽流感病毒H5N1与人体组织间可能存在某种关联,这或许可为禽流感病毒感染和致病研究提供参考。
Objective: To investigate the biological characteristics of monoclonal antibodies against avian influenza virus( AIV). Methods: Monoclonal antibodies( m Abs) against AIV H5N1 were prepared and it’s characteristics were identified including subtype,titer,hemagglutination inhibition activity and cross-reactivity with other influenza viruses. Besides,Western blot and immunohistochemical staining methods were conducted to test the combination of antibodies and antigen( H5N1) and human normal tissues. Results: Immunohistochemical analysis showed that 2 m Abs( H5-32 and H5-35) cross-reacted with human tissues kidney and pancreas respectively. Conclusion: These data indicated that there have some association between the AIV H5N1 with human tissues,which may provide reference for the study on avian influenza virus infection and pathogenicity.
