摘要: 目的扩增及克隆C57BL/6j小鼠titf-2基因并利用小鼠骨髓间充质细胞进行表达.方法从C57BL/6j小鼠肝脏组织中提取基因组DNA,用PCR从中扩增出titf-2基因片段.将titf-2基因片段插入载体pMD18-T中,经全自动序列分析仪测序正确后,再克隆至表达载体pBROAD3-mcs中,构建重组表达载体pBROAD3-mcs-titf-2,并转染小鼠骨髓间充质细胞进行表达.用羊抗鼠TTF-2多抗IgG对表达产物进行Western Blot签定.结果 DNA测序结果证实,获得titf-2基因片段,大小与理论值相符;Western Blot分析表明,表达出TTF-2约为4.2KDa大小的蛋白.结论成功扩增、克隆titf-2基因,并在小鼠骨髓间充质细胞中得到表达,为下一步建立titf-2转基因小鼠模型奠定了基础.

Abstract: Objective To amplify and clone the C57BL/6J mouse titf-2 gene and express its protein in the mouse marrow mesenchymal cell.Methods The DNA encoding the C57BL/6J mouse titf-2 gene was amplified by PCR from the mouse liver tissue.The titf-2 gene was inserted into plasmid pMD18-T.After sequencing,The titf-2 gene was cloned into eukaryotic expression vector pBROAD3-mcs to construct the recombinant expression vector pBROAD3-titf-2 and it was used to transfect the mouse marrow mesenchymal cell.The expression prod...-
