| Abstract: | Objective: To construct a eukaryotic expression plasmid pcDNA3.1 (-)-Humanin. Methods: The recombinant plasm pGEMEX- 1-Humanin was digested with restriction endonucleases BamH I and Hind Ⅲ and the Humanin gene fragments, abo 100 bp length, were obtained. Then the Humanin gene fragments were inserted into eukaryotic expression vector pcDNA3.1 (-) and the recombinant plasmids pcDNA3. l(-)-Humanin were identified by sequencing. Results: Recombinant plasmid DNA succesfully produced a band which had the same size as that of the Humanin positive control. The sequence of recombinant plasmids accorded with the Humnain gene sequence. Conclusions: A eukaryotic expression plasmid of Humanin was successfully constructed. |
