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. SARS-COV-2 Spike S1 NTD Protein (His & Flag) is expressed in HEK293 mammalian cells with C-His-Flag tag. The predicted molecular weight is 35 kDa and the accession number is A0A6G7K2L4.
Molecular Weight:
35 kDa (predicted). Due to glycosylation, the protein migrates to 55-70 kDa based on Tris-Bis PAGE result.
