摘要
提取新鲜人胎盘组织的总RNA,利用RT-PCR技术扩增出膜联蛋白V(Annexin V)基因的编码序列,将扩增产物克隆到真核表达载体pCMV5并转化到大肠杆菌DH5α中.对重组质粒进行DNA测序,其测序结果完全正确.成功地从人胎盘组织中克隆出Annexin V的全长基因并构建了该基因的真核表达载体,为今后该基因的表达及其生理作用的研究奠定了基础.
Annexin Ⅴ gene containing EcoR Ⅰ and Hind Ⅲ endoenzyme site is produced by using RT-PCR technique from fresh human placentas. The Annexin Ⅴ gene is digested by double enzyme (EcoR Ⅰ and Hind Ⅲ) and inserted into expression vector pCMV5. The ligation products are transformed into E. coli DH5α. Recombinant plasmid is determined by restriction endonuclease digestion and PCR methods. The result is in agreement with the expected data and DNA sequencing is carried out also. The Annexin Ⅴ gene is cloned and the recombinant eukaryotic expression plasmid containing human Annexin Ⅴ gene is successfully constructed. The production and functional assay of human Annexin Ⅴ protein are in progress.
