Specification

• Cat#: THP-0543
• Product Name: Recombinant SARS-CoV S-trimer Protein (C-6His)
• Description: Recombinant SARS-CoV S-trimer Protein is generated using a Mammalian expression system. The target gene encoding Ser14-Gln1190 is expressed with a C-terminal 6His tag.
• Molecular Weight: 134.9 kDa
• Introduction: The coronavirus spike (S) glycoprotein features protrusions that selectively bind host cell receptors such as ACE2, DPP4, APN, CEACAM1, and sialic acids. The S protein is crucial for viral attachment at the onset of infection. It is a large type I transmembrane protein composed of S1 and S2 subunits. S1 contains the receptor-binding domain (RBD) for cell recognition, while S2 contains elements required for membrane fusion. The S protein is vital for eliciting neutralizing antibodies, T-cell responses, and protective immunity.
