Description:    Recombinant SARS-CoV-2 (Omicron BA.2) S-RBD 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.
Species/Host:    HEK293
Molecular Weight:    The protein has a predicted molecular mass of 51.4 kDa after removal of the signal peptide. The apparent molecular mass of S-RBD(Omicron BA.2)-hFc is approximately 55-70 kDa due to glycosylation.
Molecular Characterization:    S protein RBD(G339D, S371F, S373P, S375F, T376A, D405N, R408S, K417N,N440K, S477N, T478K, E484A, Q493R, Q498R, N501Y, Y505H)(Arg319-Phe541) hFc(Glu99-Ala330)
Purity:    The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining.
Formulation & Reconstitution:    Lyophilized from nanodisc solubilization buffer (20 mM Tris-HCl, 150 mM NaCl, pH 8.0). Normally 5% – 8% trehalose is added as protectants before lyophilization.
Storage & Shipping:    Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing). Lyophilized proteins are shipped at ambient temperature.
