Differential proteomic analysis of Panax ginseng from different habitats

Objective: To research differences between Ginseng protein from Panax ginseng of different origins. Methods: The extraction methods of ginseng protein and the experiment conditions of membrane hybridization were established,and peptide arrays method was applied to hybrid with ginseng protein. Results: There were significant differences in Ginseng protein from P. ginseng of different origins,in which the difference was significant between high latitude regions( XK、ML) and low latitude regions( CB、JA、XS),and the difference was not obvious between the same latitude regions( XK and ML or CB、JA、XS). Conclusion: The polypeptide array technology can be used to research the ginseng protein of P. ginseng of different origins and different growth conditions. Ginseng protein from different regions showed obvious difference. In addition,ginseng protein expression characteristic map can be used for the identification of P. ginseng.
