SARS-COV-2 S1 (670a.a, HEK293, Fc-Avi)

SARS-CoV-2 S1 Protein, in its Spike protein S1 form, initiates infection by attaching the virion to the cell membrane through host receptor interaction. Simultaneously, Spike protein S2' acts as a viral fusion peptide, revealing itself after S2 cleavage during virus endocytosis. SARS-COV-2 S1 Protein (670a.a, HEK293, Fc-Avi) is the recombinant Virus-derived SARS-COV-2 S1 protein, expressed by HEK293 , with C-Avi, C-hFc labeled tag.
