| 摘 要： | 应用RT-PCR方法从人子宫内膜组织总RNA扩增出hLIF的全长基因,然后将其克隆至pcDNA3上,成功构建了重组真核表达载体pcDNA3/hLIF.利用脂质体介导将这一表达载体导入COS-7细胞和CHO-K1细胞,分别获得了hLIF的瞬时表达和稳定表达,为进一步进行hLIF生物学功能研究和hLIF在哺乳动物细胞中的高表达研究奠定了基础.

| Abstract: | The whole gene encoding hLIF protein was amplified from totahis gene was cloned into pcDNA3 vector and constructed the pcDNA3/hLIF expression vector.And finally,pcDNA3/hLIF was introduced into COS-7 cells and CHO-K1 cells by using the method of lipofectin transfection,and transient expression and stable expression of hLIF protein was obtained respectively.These results provide bases for further researches for biological function of hLIF and its high expression in mammalian cells. |
