Abstract:
Objective To insert VEGF-R3(FIT-4)gene fragment into cloning vector and identify it.Methods By T-A cloning,the VEGF-R3 gene fragment amplified by RT-PCR was cloned on the PGEM-T Easy plasmid vector and transfected into E.coli JM109.the recombinant clones were screened by"white-blue plaque selection" and tested by the methods of single restrictional enzyme.Results The VEGF-R3 gene fragment amplified by RT-PCR showed a smear after the electrophoresis on agarose Gel and obtained white clones by"white-blue plaque selection".The electrophoresis result of the recombinant clones tested by the single restrictional enzyme was accordant with expectant result.Conclusion The recombinant clones through the methods T-A may be used in the further gene expression and gene therapy studies.
