SARS-CoV-2 (Alpha) S protein RBD , hFc Tag

Description :Recombinant SARS-CoV-2 S protein RBD (N501Y) protein with C-terminal human Fc tag Background : SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) also known as Covid19 (2019 Novel Coronavirus) is a virus that causes illnesses ranging from the common cold to severe diseases. The spike protein is a type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which accounts for recognizing the cell surface receptor, ACE2. S2 contains basic elements needed for the membrane fusion. Recent publications indicate that S1-RBD domain can induce virus neutralizing-antibody and T cell response. Molecular Characterization: mass of 51.3 kDa after removal of the signal peptide.The apparent molecular mass of RBD (N501Y) -hFc is approximately 55-70 kDa due to glycosylation. Tag :C-Human Fc Tag
