Study on Purification and Immunogenicity of Rabies Virus Nucleoprotein

  • Available online: 05 February 2001
  • Abstract:In order tO establish the optimum condition for purification of the nucleopmtein(NP)of rabies virus by immuno0finity chromatography,the efficient and non-danatulative eluants(Mg-d)Ⅵ忸s obtained by using ELISA elution model;furthermore.it didn’t damage the activity of NP.Two kind of NPs,expressed by Te— combimnt vacclnia virus(rVac—N)and~,o3mbinant haculovirus(BRN),were purified by a Sepharose CL 413 column and a 2C12一Sepham~e 4B oolurrm ByWestern-blot and SDS-PAGE.highpurityandgood antigenie,~ intact NPs were identified. purified ribonucleopmtein(RNP) rabies virus 5aG strain was also 0brained.
