摘要: 目的:制备抗激活素受体相互作用蛋白 1(ARIP1)抗体并探讨其应用。方法: 在大肠杆菌BL21中表达GST-ARIP1融合蛋白,以该蛋白作为抗原免疫新西兰家兔,制备抗ARIP1的多克隆抗体。应用该抗体进行免疫组织化学染色,分析ARIP1在小鼠脑组织的分布。结果:制备的兔抗ARIP1多克隆抗体可以特异识别ARIP1,而与ARIP2无交叉反应。初步应用制备的抗体进行免疫组织化学染色,ARIP1在小鼠大脑组织主要表达在下丘脑及海马。结论:成功地制备了抗ARIP1多克隆抗体,该抗体可用于ARIP1成熟蛋白表达的免疫组织化学染色分析。

Abstract: To prepare anti-activin receptor-interacting protein 1 (ARI P1) polyclonal antibody.Methods The GST-ARIP1 fusion protein was expressed in E.coli BL21.A polyclonal antibody against ARIP1 was obtained by immunizing a rabbit with the purified GST-ARIP1 and the localization of mature ARIP1 protein in mouse brain tissues was detected by immunohistochemistry using the prepared anti-ARIP1 antibody. Results Anti-ARIP1 polyclonal antibody could bind specifically with recombinant ARIP1,but not recombinant ARIP2.Immunohistochemical staining showed that ARIP1 mainly expressed in hypothalamus and hippocampus using the prepared anti-ARIP1 antibody. Conclusion The polyclonal antibody against ARIP1 has been successfully prepared and can be used to do immunohistochemical analysis for ARIP1 protein expression.
