| Product Description | Recombinant SARS-COV-2 Spike S1 Protein is expressed from HEK293 with hFc tag at the C-Terminus.It contains Val16-Arg685. |
Product Background |
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. |
