Cloning of HBsAg Gene of Hepatitis B Virus in to an Expression Vector

2003 Flora Infeksiyon Hastalıkları ve Klinik Mikrobiyoloji Dergisi  
In the present study, the surface antigen (HBsAg) of HBV was amplified by polymerase chain reaction (PCR) and cloned into an expression vector. For this purpose, HBV DNA was obtained from a patient with chronic HBV infection. Then, the PCR product of HBsAg gene of HBV was cloned into pcDNA3.1/V5 HisTOPO vector. The resulting recombinant plasmid, termed pFHBsAg, was transformed into jM109 competent bacterial cells. The presence of the HBsAg gene was confirmed by PCR screening assay. Moreover,
