| 摘要: |
| 采用RT-PCR方法成功地从人胎盘组织扩增出hIGF-Ⅱ基因。将其连入表达载体pET30a(+)质粒中,SDS-PAGE结果证明,pET30a(+)-hIGF-Ⅱ在大肠杆菌BL21(DE3)中获得高效表达,目的蛋白占总菌体蛋白35%左右。 |

| Abstract: |
| Human IGF-Ⅱ gene was successfully amplified from human placenta with RT-PCR method,then cloned it into expression vector:pET30a(+).pET30a(+)hIGF-Ⅱ was highly expressed in BL21(DE3) and the recombinant hIGF-Ⅱ was about 35% of total proteins measured with SDS-PAGE. |
