Findings from Jilin University in Molecular Biology Provides New Insights (Article expression, purification, and characterization of Cu/ZnSOD from Panax ginseng)

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Life Science Research have been published. According to news originating from Changchun, People's Republic of China, by NewsRx correspondents, research stated, "Superoxide dismutase (SOD) has a strong antioxidant effect, but the traditional SOD extraction method is not the most efficient method of SOD amplification. In this study, we report the cloning of the Cu/ZnSOD gene from Panax ginseng into a temperature-regulated expression plasmid, pBV220."

Our news journalists obtained a quote from the research from Jilin University, "Cu/ZnSOD inclusion bodies were expressed in E. coli at a high level. Then, the inclusion bodies were purified by ion-exchange chromatography and molecular sieve chromatography. Finally, we obtained stable SOD in the bacterial broth, with a protein content of 965 mg/L and enzyme specific activity of 9389.96 U/mg."

According to the news editors, the research concluded: "These results provide a foundation for future studies on the antioxidant mechanisms of ginseng and the development and application of ginseng Cu/ZnSOD."

The news correspondents report that additional information may be obtained from D. Ding, Dept. of Gastrointestinal Surgery, China-Japan Union Hospital, Jilin University, Changchun 130000, People's Republic of China. Additional authors for this research include S. Liu, K. Wang, L. Huang and J. Zhao (see also Life Science Research).
