摘要
目的:构建pBiFC-VN173-Olig1和pBiFC-VC155-Id2真核表达质粒,并进行鉴定。方法:以pEGFP-N3-Olig1真核表达质粒为模板扩增出Olig1基因,与pBiFC-VN173载体连接,构建pBiFC-VN173-Olig1真核表达质粒;利用RT-PCR方法从新生大鼠脊髓中提取Id2基因片段,与pBiFC-VC155载体连接,构建pBiFC-VC155-Id2真核表达质粒。对此2种质粒进行酶切鉴定、测序。结果:通过酶切鉴定、测序,证明pBiFC-VN173-Olig1和pBiFC-VC155-Id2重组质粒序列和编码框均正确构建成功。结论:成功构建了pBiFC-VN173-Olig1和pBiFC-VC155-Id2真核表达质粒,为进一步在活细胞内研究Olig1和Id2的相互作用提供了实验基础。
Objective:To construct and identify pBiFC-VN173-Olig1 and pBiFC-VC155-Id2 eukaryotic expression plasmid for bimolecular fluorescence complementation(BiFC)assay.Methods:Rat olig1 gene from pGFP-N3-Olig1 eukaryotic expression plasmid was amplified by PCR.And rat Id2 gene from RNA of neonatal rat spinal cord was amplified by RT-PCR.The Olig1 gene was inserted into BiFC eukaryotic expression vector pBiFC-VN173 and Id2 gene was inserted into pBiFC-VC155,which were used to construct recombinant expression vector pBiFC-VN173-Olig1 and pBiFC-VC155-Id2,respectively.The recombinant vectors were identified by restriction enzyme digestion and DNA sequencing.Results:The restriction enzyme digestion and DNA sequencing results showed that the sequences and open read frames of the two vectors were completely concordant with experiment design.Conclusions:The pBiFC-VN173-Olig1 and pBiFC-VC155-Id2 were successfully constructed.These provide an experimental base for further research on interaction between Olig1 and Id2 in vivo.
