Firstly, the pGL3-Control vector was reconstructed , the pGL3-Enhancer vector deletious of SV40 promoter gene was obtained . Then the IFN-β promoter gene was cloned into the pGL3-Enhancer vector and pGL-IP21, the Luciferase reporter plasmid with IFN-β promoter was OK. The availability of pGL-IP21 was verified by NDV ,the inductor of IFN-β, the Luciferase activity was assayed in cells transfected with pGL-IP21 by Luminometer.

In order to develop a safe and effective immunoadjuvant to enhance the immunity and resistance of animals against infection, a novel CpG Oligodeoxynucleotides containing 11 CpG motifs was synthesized and inserted into the VR1012 plasmid, designated as VR1C. Then the recombinant VR1C was entrapped with Chitosan nanoparticles prepared by the method of ionic cross linkage, and employed to inject muscularly 3-weeks old Kunming mice; the blank VR1012 packed with CNP and saline were used to inoculate mice as the control groups. 28 days after inoculation, all mice were orally fed with 0.4ml 2x108CFU/ per mouse virulent hemorrhagic enteritis E. coli to challenge the resistance against infection.
