| 摘 要： | 根据GenBank中已发表的Lhx2基因序列设计引物,采用RT-PCR方法,从陕北白绒山羊皮肤组织克隆Lhx2基因编码区cDNA,对其进行生物信息学分析,并构建原核表达载体pET-Lhx2,在大肠杆菌BL21(DE3)中表达。最终获得陕北白绒山羊Lhx2基因,长1 221bp;酶切和测序结果显示,原核表达载体pET-Lhx2构建成功;SDS-PAGE和Western blot分析表明,重组原核表达载体在大肠杆菌中成功表达出目的融合蛋白。

| Abstract: | The cDNA of Lhx2 gene was amplified from the skin of Shaanbei White Cashmere Goat by RT-PCR using one pair of primers which was designed and synthesized according to the Lhx2 gene sequence in GenBank.The biological information analysis was performed with it.The prokaryotic expression vector pET-Lhx2 was constructed and expressed in E.coli BL21(DE3).The cDNA of Shaanbei White Cashmere Goat Lhx2 gene was 1 221 bp.Restriction enzyme mapping and sequencing showed that prokaryotic expression vector was constructed successfully.SDS-PAGE and Western blot showed that the recombinant prokaryotic expression vector expressed the fusion protein(65 ku)successfully. |
