Title

NOVEL RECOMBINANT TRACEABLE C-MET ANTAGONIST-AVIMER ANTIBODY MIMETIC OBTAINED BY BACTERIAL EXPRESSION ANALYSIS

Pages

  9-14

Abstract

 Background: Avimers are originally types of artificial proteins with multiple binding sites for specific binding to certain antigens. Various radioisotopes and nanoparticles link these molecules, which are widely used in early detection in tissue imaging, treatment and study on carcinogenesis. Among these, c-Met antagonist avimer (C426 avimer), with ability to bind the c-Met receptor of tyrosine kinase (RTK) is an attractive candidate for targeted cancer therapy. In this study, a novel traceable C426 avimer gene was designed and introduced by adding the 12nt tracer binding site encoded four specific amino acid residues at the C-terminal region of C426 avimer coding sequence.Methods: The 282 bp DNA sequence encoded 94aa avimer protein was synthesized and sub-cloned into prokaryotic pET26b expression vector. The expression of the mature peptide encoding the traceable avimer molecule was carried out in Escherichia colistrain BL21 using IPTG (Isopropyl b-D-1-thiogalactopyranoside) induction process.The expression level of the 11kDa traceable avimer was studied by SDS-PAGE, western blot and ELISA analysis.Results: Docking analysis of C426 avimer protein and its ligand c-Met showed that the traceability related changes happened at the best conformation and optimal energy. The SDS-PAGE, western blotting and ELISA analysis results demonstrated that the expression of the 11kDa C426 avimer molecule was detectable without any degradation compared with the control group.Conclusion: Concerning the consequences of this work, this new approach can be widely used in the medical field and provide an opportunity to evaluate the affinity and traceability features.
