Abstract: Objective: to construct CEA scFv antibody-conjugated alliinase fusion gene eukaryotic expression vector and expression in Pichia pastoris expression. Methods: according to the design of alliinase gene sequences upstream and downstream primer, respectively, the introduction of EcoRI and XbaI restriction endonuclease sites. For the preservation of the pGEMP-T-Alliinasee plasmid as template for the PCR amplification. From Escherichia coli extracts pPIcz alpha C plasmid, then, PCR product and pPIcz alpha C plasmid respectively by EcoRI and XbaI double enzyme, pPIcz alpha C-Alliinase recombinant plasmid construction. In order to save pGEMP-T-CEA as template, redesigning primer, respectively, introduce XhoI and EcoRI restriction endonuclease sites, PCR products, the PCR product and pPIcz alpha C-Alliinase respectively by EcoRI and XhoI double digestion, constructing pPIcz alpha C-Alliinase CEA recombinant plasmid. Double enzyme, PCR identification and sequencing analysis. The identification of the correct pPIcz alpha C-Alliinasee-CEA plasmid transformation to the Pichia pastoris expression, SDS-PAGE electrophoresis and Western Blotting detection target protein expression. Results: the successful construction of single chain antibody1CEA alliinase fusion gene eukaryotic expression plasmid, size of about5600bp. The 2fusion protein in Pichia pastoris gets preliminary expression, molecular weight of about78KD. Conclusion: CEA single chain antibody of alliinase gene fusion can be obtained in Pichia pastoris expression.
