[Cloning and expressing of golgi protein73 gene fragment and preparation of monoclonal antibodies against the recombinant protein].
Objective: To clone and express human Golgi glycoprotein73 protein, and prepare the monoclonal antibody (mAb) against the protein.
Methods: GP73 gene was amplified from HepG2 cells by RT-PCR, then ligated with pQE31 to form recombinant plasmid pQE-GP73 and transformed into E. coli BL21. The protein induced by IPTG was purified by 6 x His-tag and used to immunize the BALB/c mice. The specific monoclonal antibodies (mAbs) were prepared by the cell fusion technique. Western Blot was used to detect specificity of mAbs.
Results: The prokaryotic plasmid expressing the recombinant protein was constructed, and the GP73 recombinant protein was expressed and purified. Five hybridoma cell lines that secreted anti-GP73 mAbs were obtained. 2 of 5 mAbs were the IgG1 subtype. Western Blot indicated the mAbs showed specific combination with GP73 protein.
Conclusion: The GP73 recombinant protein is highly purified and has strong antigenicity. The anti-GP73 mAbs were prepared successfully.
