Recombinant SARS-CoV-2 Spike RBD

• Background:

  The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensinconverting 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.
