Abstract: In order to develop subunit vaccine of mink enteritis virus,the immunogenicity of mink parvovirus protein NS1 and VP2 had been evaluated.Two pairs of primers were designed,and the full-length NS1 and VP2 genes had been amplificated,and then prokaryotic expression vector pET-32a-NS1,PET-32a-VP2 were constructed.After the analysis of SDS-PAGE and Western blotting,target proteins had been purified by His-Bind affinity chromatography.The immunogenicity of purified protein NS1 and VP2 were evaluated by serum ELISA testing,after inoculated BALB/c mouse.The results showed that the molecular mass of NS1 and VP2 protein were 83 and 67 ku by SDS-PAGF and Western blotting;Although both target protein NS1 and VP2 had the ability to induce BALB/c mouse to produce anti-MEV specific antibodies,the level of antibodies induced by the protein VP2 was higher than protein NS1.Mink parvovirus protein VP2 was more suitable for the development of subunit vaccine.

Key words: mink parvovirus; prokaryotic expression; recombinant protein
