| Abstract: | The fibroblast activation protein α(FAPα)gene was amplified from BALB/c mouse embryo fibroblasts(EF)by RT-PCR and cloned into expression plasmid pTd-FL-N.Subsequently,the recombinant plasmid pTd-FL-N/FAPα was transformed in E.coli Stbl3.The recombinant colonies were screened and identified by restriction enzyme digestion,PCR detection and sequencing.These results showed that the expression plasmid was correctly constructed.The human embryonic kidney cells(HEK293)were transfected with the expression plasmid.G418 screening and Western blot displayed that the stable cell line which could highly express the FAPα protein was established successfully.Meantime,the expression of FAPα on the cell membrane was confirmed by flow cytometry. |
