SARS-COV-2 S1 NTD (HEK293, His-Flag)

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 NTD (HEK293, His-Flag) is the recombinant Virus-derived SARS-COV-2 S1 protein NTD, expressed by HEK293 , with C-His, C-Flag labeled tag.
