Chemical Synthesis and Cloning of Panax ginseng Peptide Gene

The sequence of ginseng peptide gene was designed and synthesized by the solid phase plasmid pUC19. Escherichia coli JM101 cells were transformed with above hybrid plasmids. Ampicillin resistant transformants were screened and identified by in situ colony hybridization and Southern blot techinques. Finally the gene sequencing was done by the Sanger dideoxy method using primer extension.
