Description
SARS-CoV-2 S protein RBD (K417N, E484K, N501Y), Fc Tag (MALS verified) | SPD-C5256-100ug| 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 RBD (K417N, E484K, N501Y), Fc Tag (SPD-C5256) is expressed from human 293 cells (HEK293). It contains AA Arg 319 - Lys 537 (Accession # QHD43416.1 (K417N, E484K, N501Y) ). The K417N, E484K, N501Y mutations were identified in the SARS-CoV-2 Beta variant (Pango lineage: B.1.351; other names: 20H/501Y.V2).
Format: Powder.
Tag: C-Fc.
