| 中文摘要: |
| 目的 通过分子生物学方法构建小鼠Orexin 2β受体(mOX2βR) C末端突变表达载体。方法 设计特异性引物,采用聚合酶链反应(PCR)技术,通过胶回收、酶切、连接、转化和测序等生物技术,构建mOX2βR突变体的表达载体。结果 成功构建mOX2βR突变表达载体,将其分别命名为mu1、mu2和mu3。结论 成功构建了mOX2βR C端不同的突变体,为进一步研究mOX2βR C末端氨基酸在信号通路中的作用奠定了基础。 |

| Objective To construct the mOX2βR mutation expression vector by using molecular biology method.Methods We had designed specific primer in our research.These genes were amplified by Polymerase Chain Reaction(PCR) using the plasmid pcDNA3.1-mOX2βR as template.The PCR product was cut by restriction endonuclease BamHⅠand XbarⅠ, connected by T4 DNA ligase and then be transformed into the E.coli competence DH5α.The construct of expression vector of mOX2βR mutants was identified by DNA sequencing.Results We successfully built mOX2βR mutant expression vector named mu1, mu2 and mu3, respectively.Conclusion The mouse OX2βR mutant expression vectors were successfully constructed, and the expression vectors can be used to study the influence of mOX2βR carboxyl terminal mutations on the signal pathways, which will lay the foundation for the development of new drugs. |
