Background and purpose: The purpose of this study was to design a recombinant vector pEFGP- N1 containing the full length of HIV-1Vpr gene. To the best of our knowledge, the cloning of Vpr gene in pEGFP_N1 is not previously done.

Materials and methods: As a source of Vpr gene the pUC19-Vpr recombinant vector was confirmed by digestion with restriction enzymes BglII and NotI in order to separate the Vpr gene. The specific primers for Vpr gene including the restriction sites of XhoI and KpnI were designed according to the multiple cloning site of pEGFP-N1 and PCR reaction was performed using the pUC 19-Vpr vector as a template. The PCR product was undergone electrophoresis and gel extraction. Digestion reaction was done on both the extracted PCR product and the pEGFP-N1vector. The recombinant pEGFP-N1-Vpr vector was achieved by the ligation reaction using the T4 DNA ligase and it was transformed into the
E-coli (DH5α) and propagated. Finally, confirmation was done through the restriction enzyme digestion and PCR amplification.

Results: The recombinant vector pUC19-Vpr was confirmed using the restriction enzymes digestion, and then Vpr gene was successfully amplified using its specific primers including restriction sites for XhoI and KpnI. The PCR product was confirmed by electrophoresis. Finally, a recombinant vector pEGFP-N1 containing the full length of human immunodeficiency virus-1 Vpr gene (pEGFP-N1-Vpr) was successfully constructed.

Conclusion: HIV-1 Vpr gene in its full length size could be ligated into the pEGFP-N1.
