Purification/Conjugué: Cette SARS-CoV-2 Spike protéine est marqué à la His tag.

Fonction: SARS-CoV-2 Spike Trimer (T95I, G142D, E154K, L452R, E484Q, D614G, P681R, Q1071H), His Tag (MALS verified)

Specificité: SARS-CoV-2 Spike Trimer (T95I, G142D, E154K, L452R, E484Q, D614G, P681R, Q1071H)

Attributs du produit: SARS-CoV-2 Spike Trimer, His Tag is expressed from human 293 cells (HEK293). It contains AA Val 16 - Pro 1213 (Accession # QHD43416.1). The mutations (T95I, G142D, E154K, L452R, E484Q, D614G, P681R) were identified in the SARS-CoV-2 variants which emerged in India (known as B.1.617). 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.

Antigène: SARS-CoV-2 Spike

Abstract: SARS-CoV-2 Spike Produits

Synonymes: E2 Protein, E2 glycoprotein precursor Protein, Surface Glycoprotein Protein, S Protein

Classe de substances: Viral Protein

Sujet: 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.
