Product Description	Recombinant SARS-CoV-2 Spike S1 (Gamma P.1/P.1.1/P.1.2) Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Gln14-Arg683(L18F, T20N, P26S, D138Y, R190S, K417T, E484K, N501Y, D614G, H655Y).
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.
