Human Papillomaviruses (HPV) infection was known to be the leading cause of cervical cancer. Cervical cancer is the fourth most common cancer among women in the world. Designing a DNA vaccine with therapeutic properties as well as prevention can have a significant impact on reducing morbidity and mortality.

Gene sequences including the immunogenic and conserved epitopes of L1 and E7 proteins of high risk papillomaviruses were designed. After synthesis of the L1-E7 fusion construct in pUC57 cloning vector, its subcloning was performed in pcDNA3.1 (-) eukaryotic vector. The concentration and purity of the recombinant pcDNA-L1E7 plasmid was determined by NanoDrop spectrophotometry.  

The gene sequence after cutting from pUC57-L1E7 by BamHI/HindIII restriction enzymes, was subcloned in the same cloning site of pcDNA3.1 (-) vector. The presence of gene was confirmed by digestion with BamHI/HindIII enzymes, as a 639 bp fragment on 1% agarose gel. The recombinant pcDNA-L1E7 plasmid was purified by endotoxin-free extraction kit for isolation of bacterial lipopolysaccharide. The concentration of the purified DNA was obtained about 1474 ng/ µl.

Cloning of the L1-E7 fusion construct in the eukaryotic vector was successful. In the next steps, the recombinant vector will be used for gene vaccine studies in vivo.
