摘要
To clone the murine α fetoprotein (AFP) gene, construct the eukaryotic expression vector of AFP and express in CHO cells, total RNA were extracted from Hepa 1 6 cells, and then the murine α fetoprotein gene was amplified by RT PCR and cloned into the eukaryotic expression vector pcDNA3.1. The recombinant of vector was identified by restriction enzyme analysis and sequencing. After transient transfection of CHO cells with the vector, Western blotting was used to detect the expression of AFP. It is concluded that the 1.8kb murine α fetoprotein gene was successfully cloned and its eukaryotic expression vector was successfully constructed.
