Background : The aim of the present study was to identify a suitable cell line for studies of recombinant protein production in eukaryotic system. After transfection, altered expression levels of RNA and its target protein were analyzed. Materials and Methods: To investigate the in vitro expression of E6 protein of human papillomavirus type 16 in cell culture, the plasmid pcDNA3-E6, and two different cell lines MCF7 and CHO were used. Following transfection, RNA expression was determined by RT- PCR and its protein target was evaluated by Western blot using SDS-PAGE gel and Anti-E6 monoclonal antibody. Results: In this study due to the low concentration of proteins in MCF7cells, RT-PCR was positive and Western blotting was negative, while RT-PCR and Western blotting were positive for CHO cell lines. Conclusion: Regarding the results, the use of CHO expression system as a tool for efficient transfection of recombinant protein production is suggested.
