Description
Biotinylated SARS-CoV-2 Spike NTD Protein (T19R, G142D, EF156-157del, R158G), His, Avitag™ | SPD-C82H3-25ug| 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: Biotinylated SARS-CoV-2 Spike NTD, His, Avitag (SPD-C82H3) is expressed from human 293 cells (HEK293). It contains AA Ser 13 - Leu 303 (Accession # QHD43416.1 (T19R, G142D, EF156-157del, R158G) ). The mutations T19R, G142D, EF156-157del, R158G were identified in the SARS-CoV-2 Delta variant (Pango lineage: B.1.617.2).
Format: Powder.
Tag: C-10×His & C-Avi.
Expression System: HEK293.
Expression Region: Ser 13 - Leu 303.
Conjugate: Biotin-labeled.
Molecular Weight: 36.3 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 36.3 kDa. The protein migrates as 45-65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
