摘要: 以纯化harpin蛋白为抗原免疫新西兰白兔,制备兔抗Harpin蛋白的多克隆抗体,经ELISA法测定抗体效价为1:2000,经亲和层析纯化,Western blot分析制备抗体与原核细胞体外表达的harpin蛋白可以特异性结合,表明该抗体的特异性良好。应用该抗体验证harpin编码基因在转基因水稻中在翻译水平的正常表达。因此,兔抗harpin抗体的成功制备,为进一步深入研究harpin的生物学功能、细胞定位以及在其他植物中的表达等奠定基础。

Abstract: Polyclonal anti-Harpin rabbit antibody has been successfully prepared by using purified harpin protein as immunogen. The ELISA titer of antiserum against harpin was about 1:2000. Western blot analysis showed that the antiserum could bind to the expression harpin protein specifically. Hrf1 gene, coding harpin, expression in transgenic rice detected by anti-Harpin rabbit antibody. The rabbit antibody against harpin can be used to study the biological function, harpin localization and hrf1 gene expression in other plants further.

Key words: harpin, polyclonal antibody, western blot, expression analysis in transgenic plants
