SARS-COV-2 S trimer (BA.2, HEK293, His)

The SARS-CoV-2 S glycoprotein is critical in infection, binding to the ACE2 receptor and allowing viral particles to attach to the host cell membrane. Cleavage of S2/S2′ triggers cell membrane fusion or internalization via endocytosis. SARS-COV-2 S trimer Protein (BA.2, HEK293, His) is the recombinant virus-derived SARS-COV-2 S trimer protein, expressed by HEK293, with C-His labeled tag, mutations, and furin cleavage site mutants.
