Construction,expression and examinations of recombiant plasmid with pmRNA IRES-hKDR / 中国基层医药

ABSTRACT

Objective To construct recobinant pmRNA IRES-hKDR and lay a primary foundation for further study of gene therapy for tumors.Methods pmRNA IRES-hKDR was obtained from pDC520 hkDR and pmRNA IRES-Luc which was reserved by our laboratory through molecular biology technology and was transfected into Hepall-6 via lipsome after identification of PCR,restriction enzyme digesting and DNA ELISA and Western blot.Results The recombiant plasmid had pmRNA IRES-hKD gene which was expressed in Hepall-6//G418 in vitro and the expressed protein was secreted out of the cells could response with specific hKDR antibody,which was identified by Western blot.Conclusion An eukaryotic expression recombiant plasmid pmRNA IRES-hKDR can be constructed successfully which provides the possibility of further researches on its anti-tumor effect.
