摘　　要：采用逆转录-聚合酶链式反应(RT-PCR)方法,从牦牛睾丸组织获得Prdm9基因的cDNA的保守区序列,克隆到pMD19-T载体中。经测序确证后,将基因克隆到原核表达载体PET32a(+),转化E.coli表达菌BL21(DE3),以IPTG诱导融合蛋白的高效表达。利用Ni柱亲和层析纯化蛋白,将得到的抗原免疫日本大白兔,获得了1∶4效价的牦牛PRDM9保守序列的多克隆抗体,可用于后续试验的研究。The conserved region of Prdm9 cDNA was obtained from yak testis by RT-PCR and cloned into pMD19-T vector.Following sequence confirmation, the cDNA was ligated with pET-32a（＋）vector and then transformed into E. coli BL21（DE3）to construct expression strains.The recombinant PRDM9 protein was efficiently expressed in the form of fusion protein through induction with IPTG.After purification by Ni-NTA, the recombinant protein was injected into Japan White rabbits, and polyclonal antibody against the conserved region of PRDM9 of yak was obtained and the antiserum was collected after the titter reach 1∶4, the antibody can be used in the future research.
