  • Source
    Biotinylated SARS-CoV-2 S protein (D614G), His,Avitag, Super stable trimer (SPN-C82E3) is the ectodomain of SARS-CoV-2 S protein that contains AA Val 16 - Pro 1213 (Accession # QHD43416.1 (D614G)) and D614G mutation, which has become increasingly common in SARS-CoV-2 viruses from around the world . The recombinant protein is expressed from human 293 cells (HEK293) with T4 fibritin trimerization motif and a polyhistidine tag at the C-terminus. Proline substitutions (F817P, A892P, A899P, A942P, K986P, V987P) and alanine substitutions (R683A and R685A) are introduced to stabilize the trimeric prefusion state of SARS-CoV-2 S protein and abolish the furin cleavage site, respectively.
    Predicted N-terminus: Val 16
  • Molecular Characterization

    This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™)

    The protein has a calculated MW of 139.7 kDa. The protein migrates as 150-200 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Labeling

  • Background
    It's been reported that SARS-CoV-2 can infect the human respiratory epithelial cells through interaction with the human ACE2 receptor. The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor. S2 contains basic elements needed for the membrane fusion.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.
