摘要: 为克隆牛抑制素α亚基基因,构建抑制素pET32a-成熟肽表达载体,从河北大厂县屠宰场采集卵巢,提取总RNA并反转录成cDNA,根据GenBank NM_174094.4 设计一对引物扩增出成熟肽cDNA,将所扩增基因插入到pET32a 表达载体BamHⅠ与HindⅢ酶切位点之间,构建重组质粒抑制素pET32a-成熟肽。结果成功构建出抑制素α亚基基因。笔者初步得到了抑制素重组质粒,为今后重组蛋白原核表达的研究奠定了基础。

Abstract: The research aimed to clone the bovine inhibin α subunit gene and construct inhibin pET32a-mat peptide expression vector. The bovine ovaries were collected from slaughterhouses of Dachang County in Hebei Province. The total RNA was extracted and reverse transcribed into cDNA. A pair of primers was designed by Primer 5.0 according to the known bovine inhibin α-subunit sequence (Genbank No.NM174094.4). Inhibin α subunit mat peptide gene was amplified by RT- PCR. Finally, cDNA of this matured peptide was further amplified and cloned into the BamH Ⅰ and Hind Ⅲ sites of pET32a expressing vector to generate the recombinant inhibin pET32a-mat peptide plasmid. The results showed that the inhibin α subunit gene was successfully constructed. The authors preliminarily obtained the recombinant plasmid of inhibin and laid foundation for the further study of prokaryotic expression of recombinant proteins.
