SARS-CoV S1 (HEK293, His-Avi)

The SARS-CoV S protein coordinates viral entry by interacting with human ACE2 and CLEC4M/DC-SIGNR receptors to attach viral particles to the cell membrane. It downregulates host tethering protein (BST2) through lysosomal degradation, antagonizing its antiviral activity. SARS-CoV S1 Protein (HEK293, His-Avi) is the recombinant Virus-derived SARS-CoV S1 protein, expressed by HEK293 , with C-Avi, C-His labeled tag.
