The eukaryotic expression plasmid (pcDNA3 CEA)containing with the gene coding for the Carcinoembryonic antigen(CEA) had been gotten with RT PCR and gene recombination *** enzymolysis,ligation and other techniques,an eukaryotic coexpression plasmid(pcDNA3 CEA/HN)containing two expression unites of CEA and Newcastle disease virus HN gene that may have the function of immunoenhancement had been *** plasmid will lay a foundation for further researching CEA nucleiotide vaccine,adjuvant and their effect of special antitumor immune.
