Description
Biotinylated SARS-CoV-2 Spike S1 Protein (T95I, G142D, E154K, L452R, E484Q, D614G, P681R), His, Avitag™ | S1N-C82E4-200ug| 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 S1, His, Avitag (S1N-C82E4) is expressed from human 293 cells (HEK293). It contains AA Val 16 - Arg 685 (Accession # QHD43416.1). The mutations (T95I, G142D, E154K, L452R, E484Q, D614G, P681R, Q1071H) were identified in the SARS-CoV-2 Kappa variant (Pango lineage: B.1.617.1; other names: 21A/S:154K).
Format: Powder.
Tag: C-10×His & C-Avi.
