Product Description	Recombinant SARS-CoV-2 Spike S1 (Delta B.1.617.2) Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Gln14-Arg683(T19R, G142D, E156G, HR157-158 del, L452R, T478K, D614G, P681R).
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.
Product Category	Recombinant Protein / Antibody discovery
