Biotinylated SARS-COV-2 Spike RBD Protein (COV-VM4BDB) Summary

Product Description	Recombinant Biotinylated SARS-COV-2 Spike RBD Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Arg319-Asn532.
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.
