Abstract: DNA immunization refers to a series of immune response processes in which the recombinant expression vector encoding a specific antigen is transferred into animal bodies,and the specific gene sequence is expressed in the animal cells and then induces to produce its specific antibody. At present,DNA immunization has become the main technical means for the research and development of various protective and diagnostic monoclonal antibodies,especially for those antigen that are difficult to express and purify in vitro. DNA immunization is superior to traditional protein immunization. DNA immunization expresses antigen in host cells and its presented manner is similar to viral infection,which can produce both humoral and cellular immunity,thereby overcoming the shortcomings of traditional protein immunization and providing an ideal technology platform for preparing high quality monoclonal antibodies. However,many challenges have been encountered in practical applications of this technique;especially the traditional intramuscular injection method is used to immunize a single plasmid DNA,which results in low delivery efficiency and antibody expression level,then leading to the low immunogenicity of DNA immunization. This article reviews the application of DNA immunoassay in the development of monoclonal antibodies,and to further discusses the DNA immunization technology in terms of its concepts,induction mechanism,vector construction,delivery methods,effects of different immunological adjuvants and its advantages and development prospects. Our aim is to provide an effective theoretical knowledge in the application of DNA immunization technology in preparing high quality monoclonal antibodies and improving its immune efficiency.
