Construction of Eukaryotic Expression Vector for Glypican-3 and Its Expression in Cell
摘要
Abstract
This work aims to construct the eukaryotic expression vector of glypican-3(GPC3)for acquiring anti-GPC3 monoclonal antibody. The GPC3 gene was amplified by PCR and was cloned into an expression vector p3XFLAG-CMV-14,and the expression vector pCMV-gpc3 was constructed. HEK293 cells were transfected with the vector by liposome,and the final results were detected by Western blot. The stably-expressed cells were collected and ground,and the high-purity GPC3 protein was obtained by affinity column. The eukaryotic expression vector of pCMV-gpc3 was constructed successfully. After the transfection to HEK293 cells,the monoclonal cell line of stably-expressed was gained by G418 screening. Western blot analysis revealed that the target protein expressed markedly. A large number of GPC3 proteins were obtained via genetic engineering and purifying technology,which laid a foundation for the biological function and application of the protein as well as the preparation of monoclonal antibody.关键词
