SARS-Associated Coronavirus Nuclecapsid is an enveloped viral componentthat contains three external structural antigens, the mains are membrane (M), envelope (E), and spike (S) proteins. Spike (S)-glycoprotein of the virus interacts with a membrenal receptor and mediates membrane fusion to grant viral entry into the target cells. therefore, S-protein has a crucial part in virus infection cycle and is the main target of neutralizing antibodies.
The E.coli derived recombinant protein contains the Nucleocapsid C-Terminal protein 340-390 amino acids immunodominant regions fused to 6xHis tag at C-terminal.
