目的:构建与鉴定骨形态发生蛋白BMP2 和转化生长因子TGFβ3 双基因真核表达载体pIRES-BMP2-TGFβ3。方法:首先,
用PCR 方法从质粒pGEMT/BMP2 中扩增出BMP2 基因全长,并将其连入双基因真核表达载体pIRES,得到质粒pIRES-BMP2,
其次,从人胚胎组织提取总RNA,反转录成cDNA,以反转录的cDNA 为模板,PCR 扩增出TGFβ3 基因全长,将TGFβ3 基因连
入质粒pIRES-BMP2;用酶切的方法筛选出阳性重组质粒,并进行测序鉴定。结果:酶切鉴定证明已将BMP2 和TGFβ3 两个基因
连入载体中,测序结果完全正确。结论:成功构建PIRES-BMP2/TGFβ3 双基因真核表达载体。 |

Objective: To construct a bicistronic eukayotic expression vector pIRES-BMP2-TGF. Methods: The BMP2 gene was
obtained from pGEMT/BMP2 plasmid by PCR. And it was inserted into bicistronic eukaryotic expression plasmid vector pIRES. The
TGFβ3 was extracted from human embryonal tissue by RT-PCR, then the gene was inserted into the plasmid pIRES-BMP2. The inserted
target genes in the plasmid were detected by restriction enzyme digestion and nucleotide sequencing. Results: The direction and sequences
of the new bicistronic eukaryotic expression vector pIRES-BMP2-TGFβ3 were correct. Conclusion: The bicistronic eukaryotic
expression vector was successfully constructed. |
