Biotinylated SARS-CoV-2 Spike S2 protein, His, Avitag™ (BA.1/Omicron) | S2N-C82E3-200ug| Gentaur Distribution US, UK & Europe
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.
Source: Biotinylated SARS-CoV-2 Spike S2 protein, His, Avitag™ (BA.1/Omicron) (S2N-C82E3) is expressed from human 293 cells (HEK293). It contains AA Ser Ser 686 - Pro 1213 (Accession # QHD43416.1 (N764K, D796Y, N856K, Q954H, N969K, L981F, F817P, A892P, A899P, A942P, K986P, V987P) ). The mutations are identified on the SARS-CoV-2 Omicron variant (Pango lineage: BA.1; GISAID clade: GRA; Nextstrain clade: 21K). Proline substitutions (F817P, A892P, A899P, A942P, K986P, V987P) are introduced to prevent the formation of aggregates in the course of protein production.
Format: Powder.
Tag: C-10×His & C-Avi.
Expression System: HEK293.
Expression Region: Ser 686 - Pro 1213.
Conjugate: Biotin-labeled.
Molecular Weight: 61.7 kDa.
Characteristics: This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™). The protein has a calculated MW of 61.7 kDa. The protein migrates as 80-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
