摘 要: | 目的:制备草鱼细胞内凋亡抑制蛋白(inhibitor of apoptosis protein, IAP)多克隆抗体,为进一步开展IAP时空差异表达分析、定位和胁迫条件下的抗凋亡功能研究奠定基础。方法:利用生物信息学技术手段设计IAP基因的特异性引物,扩增长度为996 bp的IAP基因片段,运用原核表达系统表达抗原,免疫新西兰大白兔,获得抗血清后,通过亲和纯化得到IAP蛋白特异性的抗体。结果:获得了高效价的IAP蛋白多克隆抗体,Western blotting可以检测到IAP在草鱼肝脏组织中的表达。结论:研究得到的IAP多克隆抗体可用于草鱼IAP表达检测、亚细胞定位及抗凋亡功能研究等。 |

Abstract: | Objective: The present study aims to make the polyclonal antibody for inhibitor of apoptosis protein (IAP) in Ctenopharyngodonidellus. Methods: We designed a pair of specific primers for IAP gene in C.idellus using bioinformatics technology, amplified a 996 bp DNA fragment and introduced this IAP gene fragment into E.coli to express a fusion protein His-IAP which then was injected into New Zealand white rabbits to prepare antiserum. Finally, specific anti-IAP polyclonal antibody was obtained by affinity purification. Results: Immunoblot analysis confirmed that IAP protein could be detected in C.idellus liver by this anti-IAP polyclonal antibody. Conclusion: An IAP polyclonal antibody is gathered and can be used for expression detection, subcellular localization and anti-apoptotic function research of IAP protein in C.idellus. |
