Recombinant 2019-nCoV Spike protein S1 (K417N, E484K, N501Y, D614G)(16-685) was expressed in CHO cells using a C-terminal His-tag. The gene accession number is MN908947.
Novel coronavirus SARS-CoV-2 has caused the pandemic of the respiratory diseases (COVID-19) around the world since 2020 (1). The spike glycoprotein (S) of coronavirus binds to the host cells through the interaction with angiotensin-converting enzyme 2 (ACE2) and facilitate viral entry into the host cell (2). SARS-CoV-2 (501Y.V2 variant) with mutations K417N, E484K and N501Y in the spike protein severely affected regions of South Africa (2). A combination of E484K, K417N and N501Y results in the highest degree of conformational modifications of receptor binding domain of spike protein when bound to hACE2, compared to either E484K or N501Y alone. E484K and N501Y increase affinity of RBD for hACE2 and the charge switch due to E484K leads to the formation of favorable contacts (3).

Product Notes
The COVID-19 (Catalog #AAA516689) 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 S1 (K417N, E484K, N501Y, D614G) 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
