SARS-CoV S RBD (sf9, Fc)

The SARS-CoV Spike glycoprotein (S) has three subunits S1, S2' and S2 through alternative splicing. S protein orchestrates viral entry by attaching the virion to the cell membrane through interactions with human ACE2 and CLEC4M/DC-SIGNR receptors. S protein also impairs target cell killing, cytokine production and down-regulates host tetherin (BST2), countering the antiviral activity of host. SARS-CoV S Protein RBD (sf9, Fc) is the recombinant Virus-derived SARS-CoV S protein RBD, expressed by Sf9 insect cells , with C-rFc labeled tag. The total length of SARS-CoV S Protein RBD (sf9, Fc) is 222 a.a., with molecular weight of ~78.9 & 54.3 kDa, respectively.
