To achieve high expression of human renal cell carcinoma-associated antigen G250 in Escherichia coli.
The gene fragments encoding the protein obtained by PCR was cloned into prokaryotic expression vector pET32a(+) and expressed in E. coli Rosseta. The immunogenicity of the recombinant protein was evaluated by Western blotting.
The plasmid pET32a(+)/G250 was constructed and expressed in E. coli Rosseta successfully. Western blot analysis showed that the recombinant protein could be specifically recognized by monoclonal antibody M75.
Efficient G250 expression is achieved in prokaryotic expression system, which may facilitate further functional study of the protein and its monoclonal antibody preparation.
