Recombinant 2019-nCoV Spike protein S1 subunit, RBD (K417T, E484K, N501Y)(319-541) was expressed in CHO cells using a C-terminal his tag, and then conjugated to Horse peroxidase (HRP). The gene accession number is MN908947.
The receptor binding domain (RBD) of the SARS-CoV-2 spike glycoprotein that recognizes the host ACE2 receptor is a major determinant of viral entry and neutralization, and is the most divergent region (1). A variant of SARS-CoV-2 carrying K417T, E484K, and N501Y mutations in the RBD was detected in Manaus, Amazonas state Brazil. This variant belongs to P.1 lineage, which descends from an earlier Brazilian variant (B.1.1.28), and has been potentially associated with an increase in transmissibility or propensity for re-infections. E484K and N501Y mutations are of particular concern since they potentially reduce antibody neutralization and increase affinity for ACE2 receptor (2). As new variants displace the first-wave virus, it is pivotal to evaluate their transmissibility, virulence and their possible tendency to escape antibody neutralization (3).

Product Notes
The COVID-19 (Catalog #AAA516691) is a Recombinant Protein produced from CHO cells and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "COVID 19 Spike RBD (K417T, E484K, N501Y) Coronavirus, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
