| The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity. |
| Recombinant SARS spike S1 protein is expressed from Expi293 with His tag and Avi tag at the C-terminal. It contains Ser14-Arg667. |
