Abstract Objetive: To investigate whether apoptosis of SGC7901 cells can be induced by the expression of the recombinant gene of anti-HER2 ScFv/tBid. Methods: The recombinant anti-HER2 ScFv/tBid gene was cloned into vector pCMV and the recombinant plasmid was transfected into SGC7901 cells. The gene expression was detected by RT-PCR and immunofluorescent staining. Cell counting was carried out to show the effect of the gene transfection on cell growth. At the same time, significant apoptotic peak was detected by flow cytometry in recombinant anti-HER2 ScFv/tBid gene transfected cells. Results: The fusion protein of anti-HER2 ScFv/tBid was observed in the cytoplasm of transfected SGC7901 cells. The transfected cells displayed typical cell growth inhibition and apoptosis. Conclusion: Fusion protein of anti-HER2 ScFv/tBid can induce apoptosis of SGC7901.
