• Product Name: Recombinant SARS-CoV-2 S Protein RBD (C-Fc)
• Description: Recombinant SARS-CoV-2 S protein RBD Protein is generated using a Mammalian expression system. The target gene encoding Arg319-Phe541 is fused with a C-terminal human IgG1 Fc tag.
• Molecular Weight: 52kDa
• Introduction: The coronavirus spike (S) glycoprotein is essential for viral attachment to host cells at the onset of infection, particularly in severe acute respiratory syndrome (SARS). The SARS-CoV S glycoprotein alone mediates membrane fusion required for viral entry and cell fusion. It acts as a major immunogen and a target for entry inhibitors. SARS-CoV-2 reportedly infects human respiratory epithelial cells via the ACE2 receptor. The S protein is a large type I transmembrane protein with S1 and S2 subunits. S1 contains the receptor-binding domain (RBD) for cell recognition, while S2 contains fusion elements. The S protein is vital for inducing neutralizing antibodies, T-cell responses, and protective immunity.
