Recombinant SARS-CoV-2 (Kappa) nCoV S Protein RBD Protein, hFc Tag

Molecular Characterization: S protein RBD (L452Rand E484Q) (Arg319-Phe541) hFc (Glu99-Ala330) Molecular weight: The protein has a predicted molecular mass of 51.2 kDa after removal of the signal peptide.The apparent molecular mass of RBD (L452Rand E484Q) -hFc is approximately 55-70 kDa due to glycosylation.Description: Recombinant SARS-CoV-2 RBD (L452RandE484Q) protein with C-terminal human Fc tagSARS-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.
