title: [The construction and expression of 6B11scFv anti-idiotypic antibody and human granulocyte-macrophage-colony stimulating factor in Escherichia coli].
abstract: OBJECTIVE
  To enhance the antigenicity of an anti-idiotypic single chain antibody 6B11 mimicking ovarian cancer antigen.
  
  
  METHODS
  Using DNA recombinant technique, a recombinant fusion protein expression vector was constructed. This vector linked 6B11scFv cDNA and human GM-CSF with a linker. Protein productions were induced with the temperature change in E. Coli and analyzed with western blot.
  
  
  RESULTS
  The expressed fusion protein can be reacted with both anti-human antibody and COC166-9(AB1 of 6B11).
  
  
  CONCLUSIONS
  The recombinant fusion protein keeps the activities of both components and may be used as tumor vaccine for ovarian cancer.
