Description
SARS-CoV-2 S protein (F817P, A892P, A899P, A942P, K986P, V987P), His Tag (MALS verified) | SPN-C52Hd-50ug| Gentaur Distribution US, UK & Europe
It's been reported that coronavirus 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.
Source: SARS-CoV-2 S protein, His Tag (SPN-C52Hd) is expressed from human 293 cells (HEK293). It contains AA Val 16 - Pro 1213 (Accession # QHD43416.1). Proline substitutions (F817P, A892P, A899P, A942P, K986P, V987P) are introduced to stabilize the trimeric prefusion state of SARS-CoV-2 S protein.
Format: Powder.
Tag: C-10×His.
Expression System: HEK293.
Expression Region: Val 16 - Pro 1213.
Conjugate: Unconjugated.
Molecular Weight: 138.2 kDa.
Characteristics: This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 138.2 kDa. The protein is cleaved at furin site and divided into S1 (16-685) and S2 (686-1213). The protein migrates as 75-85 kDa, 90-100 kDa and 150-160 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
