Published: July 2010

Aim: Preparation of monoclonal antibody (mAb) against GP73 protein.

Methods: The N-terminal peptide (AAAERGAVELK) of GP73 protein was displayed on T7 phage, the recombinant phage was amplified and used as the immunogen to immunize mouse to produce antibody. The titer of the antiserum and the positive hybridoma clones which secreted the mAb against GP73 protein were detected by ELISA. The mAb specificity was assayed by ELISA and Western blot.

Results: The high specificity mAb against GP73 protein was selected from the mouse immunized with the recombinant T7 phages displaying the epitope of GP73 by cell fusion and screening.

Conclusion: The appropriate protein epitope displayed on T7 phage could be used as alternative antigen to immunize animals to make specific antibody against the corresponding native protein.

Highly sensitive electrochemical immunosensor for golgi protein 73 based on proximity ligation assay and enzyme-powered recycling amplification.

Golgi protein 73 (GP73) is a potential hepatocellular carcinoma serum marker with better sensitivity and specificity. In this study, a highly sensitive electrochemical immunosensor which combines the highly selective proximity ligation assay (PLA) and highly efficient enzyme-powered recycling amplification has been developed for GP73 determination. PLA is triggered by affinity binding of two labelled antibody-DNA (P1-RAb and P2-MAb) to target protein, resulting in increased specificity.

Background: Serum Golgi protein 73 (GP73) as a novel and potential marker for diagnosing hepatocellular carcinoma (HCC) have been found to be elevated in HCC patients and associated with clinical variables representing tumor growth and invasiveness. The aim of this study was to prepare a pair of monoclonal antibodys (mAbs) against GP73 and develop a newly designed double-antibody sandwich enzyme-linked immunosorbent assay (s-ELISA), which would be used in the detection of serum GP73 (sGP73) as well as in the diagnosis of HCC.

Materials And Methods: Produced by prokaryotic expression, the purified recombinant GP73 (rGP73), produced by prokaryotic expression, was used to immunize the Balb/c mice.

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.

Recently, serum Golgi protein 73 (GP73) levels have been found to be elevated in patients with hepatocellular carcinoma (HCC), and GP73 has been proposed as a novel marker for HCC. However, GP73 levels in patients remain controversial due to the specificity of the anti-GP73 antibody-based enzyme linked immunosorbent assay (ELISA). Therefore, an anti-GP73 antibody with high specificity was highly demanded.
