Cloning and Expression of Nucleocapsid Genes of Hantaviruses in Escherichia coli
초록
영어
Hantaviruses are rodent hosts-borne viruses belonging to the family Bunyaviridae, and are etiologic agents for two acute diseases, i.e., Haemorrhagic Fever with Renal Syndrome (HFRS) and Hantavirus Pulmonary Syndrome (HPS). There have been a lot of reports on prophylactic vaccines and diagnostics for the diseases, but most of viral antigens have been prepared by eukaryotic cell culture. Nucleocapsid proteins of Hantaviruses are known as the major viral antigens. Thereby, we prepared nucleocapsid genes of Hantaan virus and Seoul virus by RT-PCR and cloned into plasmid vectors, pET-3a and pKK223-3. Both genes were expressed in Escherichia coli with higher expression level of Seoul viral nucleocapsid protein compared to that of Hantaan in pET-3a. Hantaan viral gene was expressed much higher level in plasmid pET-3a that in pKK223-3. About 30% of expressed nucleocapsid protein was soluble and the rest was remained in insoluble fraction.
