pIRES2-EGFP-LR真核表达载体的构建及其在293T细胞中的表达
Construction of eukaryotic expression plasmid pIRES2-EGFP-LR and its expression in 293T cells
摘要
Abstract
To explore the physiologic function of laminin receptor (LR) and its role in the development of diseases,a LR gene was amplified by RT-PCR with the total RNA extracted of the cultured cortical neu-rons of SD rats as template. To construct pMD18-T-LR, the amplified gene was cloned into the vector pMD18-T. The LR gene from pMD18-T-LR digested by restriction enzymes Bgl Ⅱ +Sal I was cloned into the eukaryotic expression vector pIRES2-EGFP with the reported gene EGFP (enhanced green fluores-cence protein). The positive recombinant was deisignated with pIRES2-EGFP-LR. After being identified by restriction enzyme digestion and sequencing,the recombinant pIRES2-EGFP-LR was transfected into 293T cells by liposomes. The expression of the recombinant pIRES2-EGFP-LR in the 293T cells was observed by fluorescence microscope and laser scanning confocal microscope. The results showed that the LR of pIRES2-EGFP-LR was successfully expressed in the 293T cells.关键词
